Since you want to get to the root cause and we're talking about USA, I believe that would be the American people.

Also - corporations are full of people. And those are all Americans. Even lobbyists are Americans.

But we should do something useful, and we're looking for easier targets to focus our rage and aggression on. I recommend those being the people that explicitly have been given power. Based on what I know about the American constitution, I believe that would be the government.
