One reason I'm fully in support of capitalism is that you're 100% free to create subsystems within it. Go get some people together, buy some cheap land in the middle of nowhere, and start your new socialist, communists, or whatever other system you might fancy utopia.

You even get an instant all-inclusive free-trade agreement with the entire United States! All you need to be able to do is produce enough within your society to pay your land tax. By contrast try to start a little capitalist society within a 'social' economic system, and it'd be off to the gulags with you.

This freedom makes it quite difficult to take the hyperbolic claims against capitalism seriously. Obviously it has lots of problems, especially in the current crony capitalist system we have, but if the solutions were as simple as e.g. 'go be socialist instead' then people could prove it even within the system itself.
