I think even within the oligarchy there are people who are not amused to see the wife of a former president competing with the son and brother of two other former presidents. You don't have to be out to dislike this system.
About a year ago, I came across an article of political dynasties in US politics. The Bushes came in at #7. The Clintons didn't make the list (the requirement for being considered a dynasty was three generations). The top 10, in descending order, were Kennedy, Roosevelt, Rockefeller, Harrison, Frelinghuysen, Adams, Bush, Breckingridge, Taft, Bayard.
That wasn't my point. I'm not saying that all oligarchs are in line with current policy. In fact, quite the opposite: Trump is clearly an oligarch, and Sanders is at least upper class.
Sorry, who are those?
