I think you are confused about what capitalism is.
Capitalism is private ownership and market pricing. It is the most efficient distributor of goods or services that we know of.
This is as opposed to fascism, which is command pricing and private ownership. How could we ever have an efficient market with the state setting the prices? It is crony capitalism under another name.
Socialism is public ownership and market pricing. Um…how can anyone sell anything when everything is owned by the state? It is a corrupt system that breeds more corruption. An honest person would not survive under socialism. A dishonest person might thrive under it.
Then we have communism, which is command pricing and public ownership. It takes the worst of both socialism and fascism. It is a wonder how anyone survives under this catastrophic arrangement.
