Introduction to Sociology/Economy

Criticisms of Socialism

There is many opinion about criticism of socialism. In the socialist system, it is inefficient and it can also be a violation of civil liberties.In socialism system,citizens can not make a decision for economic rationally.Because there is not enough information about  prices and productive quotas.Many sociologists argued that  the social control over distribution of wealth and private property advocated by socialists cannot be achieved good economy.It can make reduced prosperity and it can take many people's economic freedom.

My opinion
Currently, in the world, many of the socialist countries has changed the capitalist system.
However,some countries has maintained a socialist system also now, North Korea which is divided with us by Korea war is such a state.Clearly, I think that in theory, socialism is an economic system that can make the country very ideal. However, when applied to reality,it was very inconsistent.Reading "Criticisms of socialism" part, I knew about socialism's problem and sociologists' opinion.

Question
If people is good-natured like the people in theory that human nature
is fundamentally good, can socialism take root in many country?
