The people with truly nothing left to lose are probably worried more about existing than voting, but I do generally agree otherwise. I think some resentment is possibly along lines of smarts/education and the roles and trappings those normally bring?

I also think there's a polarisation between people predisposed mentally for survival and others for thriving. Scott Alexander has a piece about this that I found very interesting: https://slatestarcodex.com/2013/03/04/a-thrivesurvive-theory...
