Socialism — You have two cows. You give one to your neighbor.
Communism — You have two cows. You give both to the state, and the state gives you milk and beef.
Capitalism — You have two cows. You sell one and buy a bull.
The problem with socialism, communism, and capitalism isn’t the ideology. Each system can work to the benefit of the people.
Almost equally, each system can work to the detriment of the people.
But the problem isn’t the -ism. The problem is the real world.
Maybe it’s human greed, power hunger, or racism. Or maybe it’s systemic incentives, privilege, or culture.
Or maybe it’s all of those things. But all those things are real-world problems, not fundamental to the academic ism.
The debate about the ism must take place in the real world.
