At what level does wealth go from "normal wealth" to "oligarch wealth"? Like, where is that line?

Also, on what planet could Bezos be described as an oligarch? Not this one. Everyone on the left and the right hates him for various reasons. The previous president hated him. This president just told his workers to unionize. Senators are constantly portraying him as Satan incarnate.

He has no political power in Washington. They hate him.
