What gets called capitalism are basically imperfect, socially evolved things that have survived and worked well enough to survive. There are definitely rent-seeking parasites out there, but some of them are like the Kim family in NK.
I mean, you can say the same about Socialism, even if you avoid the nationalistic flavors thereof. It's not like Russia, China, Cambodia, etc. were peaceful and it's odd that you point to the reaction to those via CIA regime change without mentioning why they might be worried about Socialist revolutionaries to begin with. Che wasn't any too peaceful, either.
