I’d say that what we see today is the logical conclusion of capitalism
Capitalism is not a political system, what is happening now is what happens when governments fail to adhere to things that were figured out more than a hundred years ago, that Capitalism needs to be reigned in, exactly to avoid it from developing into monopolies and an oligarchy. USA has allowed that to happen, because of the (bitter) "sweet" profits, and with an already dysfunctional democracy, USA is very vulnerable to abuse of the power of extremely strong companies and even individuals now.
if humanity wants to survive in the long run, there is no easy way out.
I think there absolutely is, that is called social democracy, which has a pretty strong track record for protecting both citizens and the environment from powerful capitalists.
But it requires a well functioning democracy, and it probably can't exist in a vacuum either. But in EU things have been trending in that direction, and EU is an excellent environment for it. USA however has a long way to go. The mentality simply isn't there currently.
