I’m answering from the perspective of living in a country with functional democracy, so it’s hard to see the power the wealthy have over it.
Lobbying and representative campaign funding are more transparent here. No party has majority seats alone, coalition governments are a necessity. Legislation is consensus driven.
Finland is very much operating in a capitalism driven economy while still supplying its citizens socialism driven security.
Capitalism is like fire. It’s a good tool, but a bad master. With appropriate legislative checks in place, it won’t get out of control.
In the States it already has, but that doesn’t mean that capitalism is bad. Just that nobody was tending the fire.
