Socialism leads to the politicization of society. Hardly anything can be worse for the production of wealth.
Socialism, at least its Marxist version, says its goal is complete equality. The Marxists observe that once you allow private property in the means of production, you allow differences. If I own resource A, then you do not own it and our relationship toward resource A becomes different and unequal. By abolishing private property in the means of production with one stroke, say the Marxists, everyone becomes co-owner of everything. This reflects everyone’s equal standing as a human being.
The reality is much different. Declaring everyone a co-owner of everything only nominally solves differences in ownership. It does not solve the real underlying problem: there remain differences in the power to control what is done with resources.
