Read the whole thing (Mises):
So the failure of socialism is not conditional on the culture, time, or place of the victims. Socialism is flawed at its core: the “collective” ownership of the means of production. As such, there is no way to enact a functioning, growth-inducing version of socialism anywhere. In practice, however, the theoretical problems of socialism give way to civil unrest, which is met with state force and results in a death toll higher than any official war ever fought.
