The part that I sometimes find the most disturbing is that they seem to think that's exactly how it is for everyone else.

And worse yet, in many ways the general welfare and common good are not irrelevant to them but something they are committed to actively opposing. General welfare and common good tend toward increasing the numbers of sane, secure, less-traumatized, reasonably-educated people who vote for more of the same in a positive feedback loop. And that is hell for anyone who's committed to a race to the bottom in what they perceive as a fundamentally dog-eat-dog world where we are no more than semi-literate primates.
