People aren't angry at capitalism. the nordic countries are capitalistic. What they are angry at are the elites and a greed-based mindset, there are poor white people, rich pro-capital gen z, and oppressed poor men. This isn't about feminism, baby boomers, and race those are linked but at the same time separate issues. This is about the idea that some people "deserved" radically more resources in life while others suffer for things outside of their control 80 to 90% of the time. At what point do we say to ourselves enough?
I don't think anyone is willing to say that poor or rich. Americans aren't willing to say it because they are on top vs many people in many countries, the Europeans aren't willing to say it because they are a beneficiary of the American-led order, China isn't willing to say it because they are growing as a superpower and want their time in the sun again, and many rich people in the global south and academics aren't acting in good faith because they too want to be on top against their own countrymen, and would likely do the same things the Americans or elite if they were in the same position, and want the same position.
