The US presidential election

As I write this, the US election is a few days away and the two main candidates are neck and neck. What puzzles me about the USA is the fixation on candidates who are rich millionaires  totally out of touch with the common man.  Looking in from the outside, it appears a broken society with a lot wrong with it. OK for those with wealth but far from OK if you happen to be at the bottom of the heap. I can't help think this is a recipe for revolution at some point in the future.
