maybe we can discuss politic science ?
i think the rise in identity politics has broken the existing model of politics.
certainly in the UK, where political allegiance has historical been down to class of birth, if your born in a lower class, you want more fairness and in a high class you want less fairness, this is largely irrelevant of how much wealth you accumulated, but as the lower class faced unfairness from birth they seldom acquire much wealth so it doesn't really matter much, and a sprinkling of middle class idealists who want more fairness when they are young and have little and then changes sides when someone wants to redistribute their wealth later in life or if they become uber rich retain their socialist ideas, but move to a tax heaven
we have been locked in a near 50 50 split for a 100 years, with each side moving the election boundaries to favour their portion of the vote.
however the last election was fought largely on the concept of British identity, a concept that is a lot stronger in the poor working class areas than it is in the more affluent areas, so the vote more or less reversed, with poor area voting for the more right wing party and the more affluent areas voting socialists
this of course is not with out an element of self regard. the rich had grown richer under the auspices of being part of Europe so both sides were still looking out for their own interests, just the party they thought would do that changed
i take the comment about trunmp appealing to inverted snobs to mean that perhaps a similar revesal is happening in america with the poor less educated being drawn by the concept of american identity and the more educated being drawn by the concept of less nationalism
