Let me say something about a so called “real socialism” (that promoted by Lenin). After The Great October Revolution in Russia it very soon had become clear that Lenin’s system based on Marx and Engels economic treaties is an academic utopia, impossible to apply in the conditions of real economic challenges of a country devastated by war and fratricidal revolutionary slaughter. The below fragment from wikipedia article about Joseph Stalin, brings some light to the sad balance of his cruel regime. And that was just the beginning, since communist and socialist regimes during years 1945-1991 devastated the economies of half of the states of today’s European Union, (which I still remember, since I was born in 1977):
“…Early researchers attempting to tally the number of people killed under Stalin’s regime were forced to rely largely upon anecdotal evidence. Their estimates ranged from a low of 3 million to as high as 60 million. When the Soviet Union collapsed in 1991 however, evidence from the Soviet archives finally became available. The archives record that about 800,000 prisoners were executed (for either political or criminal offences) under Stalin, while about 1.7 million died in the GULAG and some 389,000 perished during kulak forced resettlement — a total of about 3 million victims.
Debate continues, however, since some historians believe the archival figures to be unreliable. For example, some argue that the many suspects tortured to death while in “investigative custody” were likely not counted amongst the executed. Also, there are certain categories of victim which it is generally agreed were carelessly recorded by the Soviets — such as the victims of ethnic deportations, or of German population transfer in the aftermath of WWII.
Thus while some archival researchers have estimated the number of victims of Stalin’s repressions to be no more than about 4 million in total, others believe the number to be considerably higher. Russian writer Vadim Erlikman, for example, makes the following estimates: executions, 1.5 million; gulags, 5 million; deportations, 1.7 million (out of 7.5 million deported); and POWs and German civilians, 1 million — a total of about 9 million victims of repression.
Some historians have also included the 6 to 8 million victims of the 1932–1933 famine as victims of repression. This categorization is controversial however, as historians differ as to whether the famine was a deliberate part of the campaign of repression against kulaks or simply an unintended consequence of the struggle over forced collectivization.
Regardless, it appears that a minimum of around 10 million surplus deaths (4 million by repression and 6 million from famine) are attributable to the regime, with a number of recent books suggesting a likely total of around 20 million. Adding 6–8 million famine victims to Erlikman’s estimates above, for example, would yield a total of between 15 and 17 million victims. Pioneering researcher Robert Conquest, meanwhile, has revised his original estimate of up to 30 million victims down to 20 million. Others, however, continue to maintain that their earlier much higher estimates are correct…”
