The observations of a fairly well informed layperson - a foreign person who's able to look at your society from outside, as opposed to staying like the frog in the frying pot and being in denial.

Here's bad news: from most non-US POVs, the US society has turned into one of the most oligarchic ones in recent history - probably only rivaled by Russia in this respect. And both mainstream parties have hugely contributed to that, since they've switched into power for ages. Denying that only speaks volumes about the one denying it, but still does not make it non-fact.
