I find that so fascinating and would love to work in sociological/psychological research of that topic. When I read the related research to that awhile ago, it really blew my mind at how insane it is but also how true. People's evaluations of the quality of current times isn't based on current times but they expect the future to be like. So inherently dumb.Go spend some time reading HumanProgress.org.
In the last 20 years extreme poverty has almost disappeared. Things are objectively so much better than ever before.
The book The Progress Paradox is a great read on just how far we've come but how people are more miserable than ever for some reason. And because of that misery, the vast majority of people actually perceive the world to be much worse off than it is...which, IMO, is laregly responsible for the state of politics today as everyone has an ax to grind and believes that the world is a horrible place.
