China is proving socialism does work. The CCP learned from the failures of the USSR.
Also, Cuba, which is under a US economic embargo, is not a good example to prove socialism doesn’t work. The economic embargo and sanctions, not socialism, are why they have shortages of certain goods.
China has not been a socialist country for many decades. It is a Capitalist economy. It is also a dictatorship.
China has the second most billionaires in the world. According to Forbes magazine:
1. US has 724 billionaires.
2. China has 626 billionaires.
3. India has 140 billionaires.
4. Germany has 136 billionaires.
These Chinese billionaires are not high party officials but businessmen. and I assume businesswomen, who own and run their own companies.
The party controls politics. But the party does not control the economy. The free market controls the economy in China.
Socialism only works if it is really Capitalism. And Capitalism doesn’t work if it is really Socialism.
