I agree, many failed countries are socialist.

Yet, if OP lives in a country that works which happens to have a majority of socialist policies, doesn't that give him the right to believe in socialist policies?

In such a scenario, the reason those countries are failed countries might not be solely because of socialism.

Cuba is communist. That's not socialism.

Many Latin American countries are socialist. The current status of those countries is mostly due to the American Military-Industrial Complex. They never stood a chance. Destroyed at every turn by the CIA.

Anyhow. Nuance is key in any discussion. We would probably have much in common in a different setting.
