The old Left-Right canard isn't working. The DINO-RINO's are one and same Swamp-creatures. The  left-leaning Bernie fans got screwed by the Upper Class as much as the Trump fans did.

It's not about the rich versus the poor either: Donald Trump is a billionaire but he isn't upper class. Green hippies in XR Superhero-Monk costumes needn't be wealthy, but they aspire to be in the popular upper class. It's about status and the pecking order. The same is true of the high school students who lecture grown ups on climate change. They might be poor but they're aiming to climb class rungs.
