Capitalism is not a choice.
Given the nature of the human mind and the material state of the world, the equilibrium state of human economies is capitalism.
To see what I mean, consider any complex system. There will be certain patterns and processes that naturally unfold in that system, while other patterns and processes do not manifest without external energy. The reason is because the former states are closer to the equilibrium state of the system while the latter are comparatively farther away.
Capitalism is like an equilibrium state, and all attempts to control capitalism require external energy. What is a concrete example of this?
Regulation has a tendency to be repealed if the public or government loses sight of why the regulation was passed in the first place. On the other hand, companies usually want regulations repealed by default. This tension between opposing forces must resolve itself, and it does in favor of companies because not only are they constantly applying pressure against regulations, but the public is often allured by the fact that many regulations lower potential levels of economic growth. Therefore it's more likely than not that regulations be repealed in the long run.
