The US is actually one the most corrupt countries on earth. What makes it worse: They always try to give lessons to the rest of the world, but meh. The result is here: Record homeless Americans, drug addicts in the streets, health crisis, education crisis, while the ruling elite (it's even more hypocritical when it's the left like Yellen) gets even richer. Time for a revolution maybe.
That's an enormous allegation. But I don't think it holds up.
The US has corruption, but actual bribery is rare, and the reason we're so outraged is because we have the attitude and expectation that no one should be corrupt. This is like saying "I wouldn't want to live in a bright room - I'd see a roach or two! I'd rather keep the lights down low."
