It wasn't strictly about income as measured in numbers, it was about social class. We have a really hard time talking about and grappling with social class in this country, but it's a fundamental force, as it is in nearly all cultures throughout history. There are many divisions and shorthand ways of trying to describe the divide, and none are fully satisfying, but one of them is that some people are economically threatened by rapidly accelerating technology, and some are economically empowered. Another is that some people are threatened by trade, and some profit from it. And so on. The global economy is changing rapidly, the distribution of wealth is becoming more unequal, and not everybody is thriving in that context. Talking about it in raw dollar terms in the aggregate has value, but it's one of many data points. Class resentment is a powerful force that has underpinned nearly every major political realignment in history, I'm not sure why everyone has such a hard time seeing it.
