Capitalism is a philosophical ideal. Like all ideals, it has limits. By the way, Socialism is also a philosophical ideal. It too has limits. The people you should be scared of are the idealists who think they know what’s best for everyone else. You write about every stupid bit of malfeasance in recent history as if it were all the fault of one ideology. It’s not.
I could recount the ills of socialism in much the same fashion as you have done for capitalism. But the truth is that every evil tyrant starts with the notion that the ends justify the means. You are pretty far out on the spectrum of idealism. You are already corrupting your language so that your reality can line up with your politics. Don’t become one of those wide eyed idealistic useful idiots. The road to Hell is paved with people just like that.
