It goes back to at least the descent from peak manufacturing back in the late 70s.  In the eighties it was inconographied by the sledgehammer destruction of imported cars.<p>That was the working class shouting out loud, hey, we&#x27;re losing our jobs in the name of globalization, but we&#x27;re not seeing benefits only turmoil (and in retrospect cheap consumerization of goods).<p>So, by and large, the blue collar working class have shouldered the repercussions from the gains enjoyed by the upper middle class and the wealthy -gains made possible through globalization.<p>In addition to that working class whites feel that they have shouldered most of the cost of equalization of justice and economics.  That&#x27;s to say when society addresses past injustices its remedy is not equally shared by the upper middle class and the wealthy.  In other words when the seriously aggrieved are given a chance at success it&#x27;s not at the cost to upper middle classers or the wealthy but mostly the working class.<p>It&#x27;s not that they are bigots and are racists and begrudge success of classes historically disadvantaged, it&#x27;s that the upper middle class and wealthy never contribute to the cost of justice.<p>I think after decades of pandering from Repubs and Dems who just patronize them they have had it and are asking for their money back.  I think this is what you see.
