This is coming a little out of left field but I think it's what fuels our current right wing political movements around the world. The world is flat. The internet made it that way. Everyone knows how the other half really live now and it's on full display on TV and TikTok and Instagram or wherever. People are pissed because the myth of upward mobility is actually a sham. For most people there is no clear path to move up unless you win the lottery. Hard work won't get you there. That combine with people behaving badly as an example of how to get what you want and it's a recipe for disaster. Americans are also conditioned to be narcissists because it's a self centered culture. You have to be because it's like the Squid Games, every person for themselves. There is no safety net from the government. If you don't play the constant squid game then you'll never survive. So, you can say we need to teach our children or some other pablum to make yourself feel better but at the end of the day, it's a game of survival and one way to get what you want is to be a jerk and entitled about everything.
