So, what's the alternative to capitalism in your book? Cause I don't see anything wrong with it. It's the only system, if unobstructed, that self-regulates. Everything else is artificially steered by humans, humans that are inherently incapable of seeing the bigger picture of all the interactions in a system as complex as our planet. And so far I haven't even read about anything that comes even remotely close to capitalism.
Democracy on the other hand... is just the opposite extreme of authoritarian regimes and ultimately not much different.
Capitalism self-regulates just fine in some cases, like it will determine the number of barbershops in a town. But there are other cases: bank runs, monopolies, etc.
Bank runs are only a problem because banks lend out 50 times more than they have.
