Communism and Capitalism: What Do the Measured Outcomes Show?
Not the ideologies, the measured results. Divided Germany and Korea, the reform breaks in China and Vietnam, Soviet growth, famine and repression, the transition, and global poverty. Every figure with its method and its confounds attached.
This compares actual governed systems, not ideologies, and it does not deliver a verdict. It sets out which outcomes are measurable, what they show, what is confounded, and which parts of the argument each side has to concede. Where two credible estimates of the same quantity differ, both are given with the reason.
What is actually being compared
The argument is usually conducted by comparing the best example of one system against the worst example of the other. That trick is available to both sides and this article does not use it.
What the historical record contains is Marxist-Leninist states as they were governed: the USSR, Maoist China, East Germany, North Korea, Cambodia under the Khmer Rouge, Cuba, Vietnam before 1986. One-party rule, predominantly state ownership, central planning. It does not contain communism as Marx described it, a classless and stateless order that no state has ever claimed to have reached. Every one of them called itself socialist or said it was building socialism. That distinction matters to what any of this evidence can settle, and it is dealt with directly further down rather than used as an escape hatch.
On the other side, Sweden and post-war West Germany are market economies with large welfare states. They have private ownership, markets and price systems. Both sides claim them, and neither is entitled to.
One more thing has to be fixed before any number means anything. Planned-economy statistics carry documented distortions: Net Material Product rather than GDP, which excludes most services; hidden inflation; quality problems; live-birth definitions that understate infant mortality. Official Soviet and East German output figures were revised sharply downward by later reconstructions. The same scepticism applies to market economies with weak statistics, and there is now a check for it: comparing reported growth against satellite night-light data shows authoritarian regimes overstating growth, whatever their economic system.
Divided Germany
Germany is the closest thing to a controlled experiment that history offers. Same language, same institutions until 1945, then two systems for forty years.
The starting point cuts against a simple reading. Before the Third Reich, the territory that became East Germany had per-capita national income around 103% of the territory that became West Germany. It was not the poorer half at the outset. By 1950 East German labour productivity was somewhere between 40% and 69% of West German, depending on which reconstruction is used, and the range itself is a measure of how bad the data is.
By the end, one 1985 reconstruction put East German per-capita national product at about 70% of the West German level in 1980. Later reconstructions measured at market prices after reunification exposed a far wider gap, closer to a third. Population moved one way throughout: West Germany grew from about 50 million in 1950 to 62 million in 1989, while East Germany fell from 18.4 million to 16.4 million, almost entirely through emigration.
Health tells a more complicated story than either side usually reports. East German men lost 0.9 years of life expectancy in 1990, the year the system ended, and did not recover the 1989 level until 1992; one study measured 3,400 excess deaths among men under 65 in 1990 and 1991 against 1989 mortality rates. Infant mortality was higher in almost every eastern state in 1991 and the east-west gap had disappeared by 1997, with eastern rates falling between 31% and 52%. So the transition itself carried an immediate mortality cost, and the convergence that followed was real.
The confound everyone reaches for is war damage and Soviet reparations, which fell far more heavily on the eastern zone than the western ones. This is where the article has to stop. No published study decomposing the East-West gap into a system component and a war-damage component could be found. Two of the three research reports behind this article said so outright. The third supplied a figure of 20% to 30% with no source attached, which is how numbers of that kind usually enter circulation. The nearest thing that exists is a 1977 analysis finding that under one set of assumptions, measured differences in inputs, trade and production structure explained at most a third of a 19% output differential, and that relaxing those assumptions let non-system factors explain all of it. That is a wide enough range to be honest about and too wide to publish as a percentage.
Divided Korea
Korea is the sharpest divergence and the worst data environment in this article.
The North was the more industrialised half at the 1953 armistice, holding most of the peninsula's heavy industry and hydroelectric capacity from the Japanese period, and several accounts have its per-capita output ahead of the South into the 1960s or 1970s. The Bank of Korea, one of the few bodies that attempts an estimate, put North Korean per-capita gross national income in 2016 at about one twenty-second of South Korea's, widening to roughly one twenty-seventh by 2019.
On health, one reconstruction estimated the life expectancy gap widening from roughly one year in 1993 to roughly ten years by 2008. An earlier comparison reported infant mortality in 1998 of 9 per 1,000 live births in the South against 54 in the North.
Every one of those figures is an external reconstruction. North Korea publishes essentially no economic statistics. The Bank of Korea builds its estimates using South Korean methodologies and prices and warns explicitly against comparing them directly with other countries. The 2008 life expectancy estimate used South Korean cause-specific mortality data as a proxy for the North. The direction of the divergence is not in doubt; the precision of any particular number is.
And the comparison cannot separate central planning from everything else that differed: the war's legacy, militarisation, near-total isolation, sanctions, and decades of aid flowing to one side.
China and Vietnam, before and after
These are the strongest cases in the pro-market argument and they contain the strongest single concession the pro-market argument has to make.
On income, the reform break is stark. China's per-capita GDP rose from 381 yuan in 1978 to 6,628 inflation-adjusted yuan by 2012, averaging about 8.8% a year. Poverty at the international line fell from around 88% of the population in 1981 to near zero. The World Bank's own summary is that the number of Chinese people below $1.90 a day fell by close to 800 million, and that China contributed close to three-quarters of the global reduction in extreme poverty.
Vietnam followed the same shape. Before Đổi Mới it was a net rice importer with food shortages and twelve-month inflation peaked at 775% at the end of 1986. After decollectivisation it became a net food exporter within about a year and the second-largest rice exporter in the world by 2005. GDP per capita rose from $598.90 in 1986 to $3,409 in 2021 in constant 2015 dollars.
Now the concession. China's life expectancy rose from 35 to 40 years in 1949 to 65.5 years by 1980, which the demographers who measured it call among the most rapid sustained increases in documented global history. Nearly all of that happened before the reforms, under Mao, and the same analysis attributes 55% to 70% of the reduction in infant and under-five mortality to school enrolment and public health campaigns rather than to income. The pro-market account owns the post-1978 income and poverty surge. The pro-planning account owns the mortality and literacy gains that came first. Neither can claim both, and the most-cited work on Chinese poverty finds much of the post-1978 drop was the country catching up for progress lost during the Maoist period, concentrated in the first agrarian-reform decade.
Both cases are also confounded. Neither country stopped being a one-party state. China kept extensive state direction alongside the markets it opened. Vietnam's recovery coincided with the end of war, export access, foreign investment and a changing world economy.
Soviet growth, and how much of it was real
The dispute is not whether the USSR industrialised. It is how fast, at what cost, and whether the model kept working.
Official statistics claimed Soviet national income multiplied about 84 times between 1928 and 1985. In 1987, two Soviet economists published an estimate in the journal Novy Mir putting the true figure at about 6.6 times. That is not a rounding difference; it is a different economic history.
Western assessments sit between and disagree with each other. A review of the CIA estimates found little evidence the agency seriously misjudged the growth record, while judging its comparative size ratios more likely to be overstated. An assessment of the Soviet critics' figures concluded their work was more careful than detractors allowed, and that the largest divergence from Western estimates falls in 1928 to 1940 rather than the post-war period. Everyone agrees on two things: the 1950s were the best decade, and growth decelerated sharply after about 1970.
What turns on it is the whole shape of the argument. The higher figures describe a slowing but functioning economy. The lower ones describe something much weaker that was near stagnation by the 1980s. There is no agreed independent reconstruction of the 1928 to 1940 output that would settle it.
Famine and repression: ranges, not totals
This is where single numbers do the most damage, in both directions. Every figure below is a range with named methods, because that is what the scholarship contains.
| Event | Scholarly range | Why estimates differ |
|---|---|---|
| Soviet famine 1931–34 | ~5.5 to 8.5 million total; Ukraine ~2.6 to 3.9 million; Kazakhstan ~1.3 to 1.5 million | Under-registration of deaths, especially infants; registration data against census back-projection |
| Great Leap Forward 1959–61 | ~15 to 55 million, with commonly cited figures around 30 to 36 million | Assumed baseline mortality, treatment of birth deficits, falsified contemporaneous statistics |
| Cambodia 1975–79 | ~1.2 to 3.4 million, central estimates ~2.2 to 2.8 million | Survey representativeness and the assumed 1975 baseline population |
| Gulag deaths 1934–53 | 1,053,829 in camps, archival count | Excludes prisons, colonies and special settlements, which are counted separately |
| Executions 1937–38 | 681,692, archival count | From an internal ministry summary; covers the Great Terror specifically |
One methodological point governs the whole table. Excess deaths and lost births are different quantities and cannot be added. One study of the Great Leap estimates 18.286 million fewer births than expected in 1959 to 1961, entirely separate from anyone who died. Totals that silently combine the two are inflated by construction.
Which brings up the number most often quoted. The Black Book of Communism put the total at roughly 94 to 100 million. Within weeks of publication two of its principal contributors, Nicolas Werth and Jean-Louis Margolin, publicly repudiated the editor's introduction in Le Monde, objecting to what they described as an obsession with reaching a hundred million and to his equation of communism with Nazism. Werth's own line was that the more you compare the two, the more the differences are obvious. They also complained that they had not been shown the introduction before publication. The substantive objection is that the total sums heterogeneous categories, executions alongside famine deaths alongside deaths in custody, and that more than half of it is famine mortality which most archive-based scholars attribute to catastrophic policy failure rather than an extermination plan. The figure is a real published claim. It is also one its own authors disowned, and both facts belong together whenever it is cited.
The same discipline applies in the other direction. Excess mortality claims are made against market and colonial systems too, including for British India and the Bengal famine of 1943, where the scholarly consensus is about 2.1 million against estimates ranging from 0.8 to 3.8 million. Political killings under market-economy dictatorships are documented: Chile's truth commissions recognise about 3,065 to 3,216 killed or disappeared between 1973 and 1990 plus 38,254 recognised survivors of political imprisonment and torture; Indonesia in 1965 and 1966 is reliably estimated at 500,000 to one million killed with 1.7 million imprisoned without trial; Argentina's disappeared are officially about 9,000 with human rights organisations citing around 30,000. Attributing those to capitalism as a system is exactly as contestable as attributing famine to communism as a system, and the article does neither.
The transition, and what caused the deaths
Russian male life expectancy fell from 63.8 years in 1990 to 57.7 in 1994. Female life expectancy fell from 74.4 to 71.2. Crude death rates rose about 40%. Most of the decline came from deaths between ages 25 and 64, with cardiovascular disease and injuries the major contributors. Estonia, Latvia, Lithuania, Ukraine and Belarus saw declines of three to nearly five years.
That much is not disputed. The cause is.
One widely cited analysis found rapid mass privatisation associated with a 12.8% short-term increase in working-age male mortality across post-communist states, with job loss as the proposed channel. A reanalysis found the correlation did not survive re-specification. Separate work showed privatisation did not systematically cut firm-level employment, which undermines the job-loss mechanism. Other researchers attribute much of the spike to alcohol, specifically the collapse of the 1985 to 1988 anti-alcohol campaign. A later Russian study comparing matched mono-industrial towns, using information on 38,339 relatives, found 13% higher adjusted working-age male mortality in rapidly privatised towns than slowly privatised ones.
The defensible reading is that the transition caused severe harm, that rapid privatisation plausibly contributed, and that nobody has isolated its share. What would settle it is individual-level longitudinal data linking specific privatisations to specific deaths, which does not exist.
The wider transition record is heterogeneous, which is itself a finding. Czech male life expectancy improved strongly while Russia, Belarus and Ukraine deteriorated. Czechia and Slovakia began from the same federation and diverged on health funding, cardiovascular mortality and alcohol and tobacco consumption. These pairs compare reform strategies and EU accession, not systems, and should not be presented as communism against capitalism.
Poverty since 1990, and what the line does
Global extreme poverty has fallen sharply. That is true at the World Bank's line, and the fall is real. Two things qualify it and both are load-bearing.
The first is China. At the $1.90 line, China accounted for about 74% of the global fall in the number of extremely poor between 1981 and 2015. At the $3.20 line, China accounted for about 138% of the reduction, because China's count fell by around 889 million while the count in the rest of the world rose by about 245 million. Any claim about global poverty is substantially a claim about China.
The second is the line itself. At the current extreme line, about 700 million people, 8.5% of the world, are below $2.15 a day. At $6.85 a day the figure is 3.5 billion, 44% of the world, and that count has barely moved since the 1990s because of population growth. Neither figure is wrong. They answer different questions, and quoting one without naming the line is the most common error in this entire argument.
A further critique holds that the extreme line is too low to represent access to basic needs at all. A cost-of-basic-needs approach, pricing an actual subsistence basket rather than converting income at purchasing power parity, produces a different historical series. That is a different estimand rather than a competing measurement of the same thing, which is why the two accounts talk past each other. A re-examination of that critique's own data concluded it mostly corroborates living standards being poorer before the transition to market economies and improving afterwards. The dispute is live.
Inequality, crises, environment, freedom
Inequality. Measured income inequality was low in Eastern bloc states, with East Germany's Gini reported around 0.185 in 1990. That measure misses what mattered: nomenklatura access to special shops, housing and travel does not appear in an income survey, so measured equality overstates real equality. In the other direction, the size of the rise in top US income shares since 1980 is unresolved, with two teams reaching materially different answers depending on how untaxed and underreported business income is allocated. Between-country inequality has fallen, driven mainly by Asian growth, while within-country inequality rose.
Crises and employment. Market economies price adjustment through unemployment and recurrent banking crises. Planned economies recorded near-full employment and absorbed the same pressure differently, through labour hoarding, chronic shortage, queueing and repressed inflation, ending in external debt crises in Poland, Romania, Yugoslavia and East Germany in the 1980s. This is a real trade-off rather than a win for either side, and it is measurable on both.
Environment. The planned economies produced some of the worst environmental damage on record. The Aral Sea lost 85% of its area and 92% of its volume between 1960 and 2012, from Soviet irrigation diversion. Czechoslovak sulphur dioxide emissions were the highest in Europe, 3,150 kilotons in 1985, falling to 86.6 kilotons by 2017. Against that, consumption-based carbon accounting moves a large share of rich countries' emissions back onto their own ledgers: emissions embodied in trade rose from 4.3 gigatonnes in 1990 to 7.8 in 2008, and on that basis the United States becomes the largest emitter. Much of the apparent environmental improvement in wealthy market economies disappears once the goods they import are counted.
Freedom. This is the least equivocal section in the article. Marxist-Leninist states scored at the bottom of every civil liberties and electoral democracy measure. Restriction of movement was a defining feature rather than an incidental one: the Berlin Wall, the Soviet internal passport system, the Chinese hukou. Migration across every divided border ran overwhelmingly from the planned side to the market side, which is the strongest single piece of revealed-preference evidence in this whole subject. The indices themselves have positions, and the article names them rather than treating any score as neutral fact.
What each side has to concede
The case for planning, as its defenders make it. Rapid industrialisation from a low base, with the Soviet 1930s to 1950s the best-documented decades. Full employment. Guaranteed housing, healthcare and education. Specific social-indicator wins relative to income: China's pre-1978 doubling of life expectancy, Cuban and Soviet literacy and infant mortality performance. One cross-national analysis of 123 countries using World Bank data found socialist states with more favourable outcomes in 30 of 36 comparisons against capitalist states at the same development level, across health, nutrition and education. It is a cross-sectional classification exercise rather than a natural experiment, and it cannot rule out selection into regime type, but it is real evidence and it is usually ignored.
What planning's defenders must concede. The migration verdict at every divided border. The growth deceleration and consumer-goods failure of every mature planned economy. The famine and repression mortality, which is in the millions even at the lowest archival estimates. And that measured income equality overstated real equality once privilege is counted.
The case for markets. The innovation and growth record. The post-1990 poverty decline. Revealed preference in migration. The Korean divergence.
What market defenders must concede. China's pre-1978 life expectancy and literacy gains, which happened under planning. That the global poverty decline is China-heavy and shrinks or reverses outside China at higher lines. The crisis and unemployment volatility of market systems. Poor American health outcomes relative to American wealth. And that consumption-based accounting erases much of the rich world's apparent environmental progress.
The case that none of this tests communism as theorised. State-capitalism theorists and Trotskyists argue the USSR and China were bureaucratic deformations rather than the stateless, moneyless order Marx described, and it is true that no state implemented that version. The partial models usually cited, Yugoslav self-management, the Paris Commune, revolutionary Catalonia, the kibbutzim, were each small, short-lived or embedded inside a market economy. They can demonstrate that particular practices are feasible. None is a functioning national communist economy, so the claim that the theorised version is untested is correct and also unfalsifiable on current evidence.
The socialist calculation debate is where that argument properly belongs, and it is a theory dispute rather than a country comparison. The original objection was that without prices for capital goods there is no basis for rational calculation; the deeper version is that prices aggregate dispersed and tacit knowledge no planner can collect. The reply was that a planning board could iterate prices toward market clearing. Modern computing addresses the arithmetic of solving large systems. It does not address information revelation, incentives, or the creation of goods that do not yet exist, which is where the dispute still sits.
What the evidence shows
1. The record tests Marxist-Leninist states as governed, not communism as theorised, and social-democratic economies are market economies claimed by both sides.
2. Germany and Korea are the closest natural experiments and both point the same way on output and migration. Neither can be cleanly attributed to the system, and no published study decomposes the German gap into system and war-damage components.
3. China's income and poverty gains came after the reforms; its life expectancy and literacy gains came almost entirely before them. Each side owns one half.
4. Famine and repression mortality is real and massive, and every credible figure is a range. The best-known total was publicly disowned by two of the book's own contributors.
5. The post-Soviet mortality crisis is established; the causal weight of rapid privatisation against alcohol and general collapse is not.
6. Global poverty has fallen sharply at the extreme line, mostly in China, and at higher lines the number of poor outside China has not fallen at all. The line has to be named for the claim to mean anything.
An agreed independent reconstruction of Soviet output for 1928 to 1940, which is the span where the estimates diverge most. A published decomposition of the East-West German gap into system and war-damage components, which would turn the strongest natural experiment into an actual measurement. Individual-level longitudinal data linking specific privatisations to specific deaths, which would settle the transition mortality dispute. And a stateless, moneyless economy operating at national scale, which would make the untested-as-theorised objection testable for the first time.
