People are after all responsible for their actions. But most people will not abandon their paradigm for new information, across all of society. That's why budging anyone into rational behavior is so hard.
As for greed: that is the story with the MAGA wealthy, and I have no excuses for them. They are in a position to be informed, can afford to care a bit about the common good, and ought to know that would be in their interests too. The uber-rich are mentally ill as far as I'm concerned with no moral compass and way too much power.
I can't accuse the working class of greed in a time when the economy just gets worse and worse for them. When people are financially stressed they choose whoever they think will help and they have tended to get it wrong throughout much of our democratic history. Like the Robber Barons putting up McKinley and tricking the masses into voting for him.
