The system for all its significant faults is the only thing stopping Amazon from employing literal slave labor in the US, or any Republican who can pay / attract enough violent followers from firebombing every abortion clinic they can find the location of. Dangerous inequality of power isn't something the Americans created; it's a feature of the world which needs to be grappled with and moderated (whatever means you set out to use to do that.)
I'm not sure what you mean by "destroyed," but revolutions which set out to thoroughly destroy the unjust system completely have a track record of making things much much worse (e.g. French Revolution, Russian Revolution). If that type of thing is what you mean by destroyed I would urge you to look at places where what you want to do has been tried, and what happened after.
