lol sorry I didn't mean to give such an American-centric answer. I forget what time I'm posting and assume most of us online are Americans.

Learned helplessness is a large part of it. People just resign to the narrative of a good party vs bad party. The good party can't win because of the bad party. Oh look the good party won an election. Well too bad because the bad party won't let the good party pass the good policy. Oh a good policy gets passed. It's actually a shit policy that helps the bad party but it must actually be good because the good guys did it and we defeated the bad party today. Then ride that victory for the next decade through another two cycles of helplessness.
