Nothing like the power concentrated in the US Government. And most of that is held and exercised in direct violation of the US Constitution. The current US Government is far more illegal than any private sector monopoly.
These two power systems are mutually reinforcing. As I said earlier in the thread, people need to look at the economic model of Nazi Germany. It featured Huge corporations in league with the Government. Each had their hands in the pockets of the other.
It was an evil system capable of horrible wrongs.
