It is our experience that I’m talking about. History has plenty of examples of how socialism fails - it’s not a matter of “victors” or not, it’s just historical fact. The decline of the soviet union, China being forced to free markets, Cambodia, Venezuela, Romania, Poland, Greece, North Korea, Ethiopia, East Germany, Cuba…
“Central planning” by the gov’t is almost always inherently inefficient. Free Markets and the people who are actually closely involved do things vastly better.
An old joke from the Soviet era: Pavel begged the Commissar of his communal dairy to give him his own cow to care for. He promised that, under his direct care, he could increase the milk production of his cow, and, as a reward for his efforts he would get to sell half of any milk above the cow’s official production level. With the extra money he earned, Pavel was able to buy some luxury goods and improve his family’s life.
Sergey went to the Commissar to complain that it was unfair that Pavel’s family was doing better than his family, and demanded that the Commissar do something about this subversion of socialist justice. The Commissar said, “Fine, I’ll give you your own cow too.” Sergey blanched and screamed, “I don’t want my own cow, you fool; I want you to kill Pavel’s cow.”
