How do you think "the rich controlling our government" would look? I can think of two possibilities: either someone rich and corrupt being elected and using the office to their own advantage and that of other rich people, or the rich influencing the government to enact the policies they want despite the people in control not also being rich. I'm not sure about you, but watching "worlds richest people line up to kiss the ring" of the new Trump administration is impossible for me to differentiate from either of those scenarios, let alone both of them.

Yes, most Trump voters are not nearly as wealthy as him (or the other executives kissing the ring), but when taxes are lowered and government services are cut due to the reduced budget, they're the ones losing more than the rich compared to a higher progressive tax rate. If the theory you're trying to disprove is that the government couldn't possibly be caused to enact policies that benefit the rich to the expense of everyone else, the fact that someone is elected by a large number of non-wealthy people doesn't demonstrate anything that would make your argument more convincing.
