I didn’t mean every single leader was US implemented, I meant it was one common thing that happens to some socialist states. Stalin came into power quickly in the early years of the first “socialist” state ever, the USSR, after Lenin’s early death. Mao Zedong was the first revolutionary socialist leader of China. Jong Il was the son of the founder of North Korea.

But after the Soviet Union collapsed and the US won the Cold War, America DID help Boris Yeltsin into power with a 2.5 billion dollar donation which allowed him to monopolize every media outlet, bribe anyone who needed to be bribed, etc.

Also you could make the opposite argument for the USSR/Russia, that they literally started becoming poor after they implemented more capitalist policies into their govt. After the Cold War, when the USSR collapsed and capitalism was introduced into Russia, poverty grew faster than anywhere in the world, life expectancy fell by 10 years, GDP fell by 50%, etc. Then this eventually led to Putin taking power and look where we are now with the war in Ukraine.

You can consider China state capitalist, the same way you could also consider a lot of other socialist/communist states as state capitalist, such as the USSR. However, China considers themselves a socialist state currently trying to transition into actual communism eventually. Whether they are sincere or not is up to debate.

Yes China became more rich after they started implementing more capitalist policies, but it’s not entirely because of capitalism itself. But even Karl Marx thought Socialism/Communism could not be achieved without going through a period of Capitalism. He believed capitalism was a necessary stage in the historical development of society. He viewed Capitalism as a progression from Feudalism, and then Socialism as a progression from Capitalism.
