Democratic socialism, Social democracy, original libertarianism of the non Rothbard variety, even pragmatic anarchocommunism. As long as they aren’t dogmatic ideologues.

A completely free market has never, and will never exist. Further markets, and currency existed before capitalism. Capitalism didn’t make them possible. Finally capitalism demands you sell for as much as the market can bare, not what is fair for the value you added. Of which capitalists generally add none. Without labor nothing gets done.

Under capitalism people that generate most of the value get the least of the capital. It’s just a more abstract way of defining and justifying oligarchy. Other than Divine Birthright.

Don’t get me wrong. I’m all for rewarding people who come up with new processes and ideas to increase efficiency etc. That’s not really what capitalism does.
