The story of the Oppressed Tiffany answered my own question about the rich Trump supporters. I forgot that it’s precisely the rich and the spoiled who feel the most Oppressed and downtrodden. They are sitting in their mansions, feeling aggrieved and hard done by. Their oppression doesn’t have to be real. To the contrary, they feel it all the more strongly the less actual cause there is for it.
The people who are actually experiencing hardship are never so aggressively mean about it.
