Not really. You don't read news and magazine articles from the 50s 60s and 70s decrying the contribution of the wealthy to the common good. You see people complaining about the taxation of the wealthy during periods of high income inequality. You see the same thing in other countries as well. Presently we tax wages heavily for middle income levels and tax capital gains at a much much lower rate.

People are pissed that the wealthy, wielding their outsized political influence have pulled up the ladder of opportunity behind themselves.

Well honestly the concentration of wealth that we see today is a new thing in society. Pretty sure the only time you're going to find the type of inequality you see today is going back to feudal times. And honestly, I doubt it would even be as bad as it is today.
