Most people I know that are concerned about economic inequality aren't super bothered by self-made billionaires (Jobs, Zuck, and Gates to a lesser degree.)
Mostly they are concerned about dynastic wealth (Waltons, Kochs) particularly when it's economic power intertwined with political power (Kennedys, Bushes, Clintons, Romneys).
Outside of San Francisco, where many people feel real downward economic pressure from tech, most of the US seems pretty happy with the self-made uber rich. In fact, I think people are downright fond of these people. The real discomfort comes when those oligarchs look to preserve dynastic wealth and power for generation after generation using trusts and other tax avoidance strategies.
