It’s not about nobody. Individuals can escape the intention. Statistically though you can have a target achieved by slowing the economy, as evident in the current situation. Of course, if the goal is not optimisation of output but of it’s distribution (with different views on what is the proper objective) then capitalism is only different to socialism in terms of definition of that objective. But similar to how we never achieved true socialism, we have never achieved true capitalism either, so I am wary of discussing on the merits of each theory on the basis of the pitfalls of their application. We still need a proper descriptive theory of our experience and socialism inadvertently is better at forming the initial angle of attack, giving a more articulate basis of discussion in terms of distribution rather than output.
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.
