Society start to become unwell only when the few “monsters” get power, especially in a unbalanced way.

And yes some have and always will try to get it, but i don’t think it’s very relevant here…

Capitalism is a very powerful way for them to use our economic system to get their power, hence why it’s a problem in itself.

And that’s also why we could have hope for a system where they can’t get power. Democracy is one solution, although limited, for example.
