I do believe many left-wing voters (around the world, but especially in this country) secretly hold serious contempt for rural areas, their lifestyles, and their values, and therefore see any sort of negative development in rural America that pushes it’s populace to urban areas as a good thing, where they can accept urban, progressive values.
Sure, but that contempt goes both ways, as another poster pointed out. And whereas Progressives want to see a society where everyone, including rural areas, ultimately prosper while the GOP and Conservatives sue culture war issues to divide us and win votes.
My best friend growing up, his entire family was on Oregon Health Plan (Medicare) and got food stamps that allowed them to survive. They still voted GOP cause of guns and the wall, despite neither issue resulting in policy beneficial to them in any way.
