I think the ancap/tradright types are really trite with the “socialism never works” claims. Capitalism doesn’t work, either. Everything works as well as it is intended to where it is used. Socialism simply appeals to (and more easily controls) shitholes, so go figure it would be associated with shitholes. Capitalism brings the bread and circuses necessary to maintain a “first-world” slave class of, ultimately, propaganda creators.
I said it before. The problems in politics are not systematic or ideological inherently. They’re people problems. Let the wrong people lead you, especially people who openly despise you, and you will be a slave with a short life span. The worst systems can work if run by good leaders who care for the people and the best systems will destroy their nations if led by those who seek to do so.
