Ludwig von Mises described exactly why socialism fails everywhere. Its not the “tragedy of the commons,” corruption, political meddling, bureaucracy, etc... those are unavoidable side-effects, not causes.
Rather, its that without a free and open price mechanism to signal to both users and suppliers how to value one thing versus another, it is impossible to properly allocate what are always finite resources. No central planner can ever overcome this.
If they bred humans to think and act like ants, then socialism would work. But then we’d be ants.
Ditto for subsidies. They actually harm the recipients, because they don’t experience the repercussions of bad decisions to prevent such decisions.
Love ol’ Ludwig!
