I am reading Hannah Arendt right now and she makes this point.
Over and over.
With a freakin hammer.
There are a LOT OF PEOPLE in the world very eager to pick a group and blame it for their problems, esp when they don't have a strong grasp of where those problems really come from.
I think it's because it's simpler and easier: You don't have to question your own possible motives or biases, you don't have to think about complicated systemic issues - you just need to blame/hate/eliminate X vulnerable group. It's all their fault.
Sometimes those problems are from themselves.
I listen to a personal finance podcast that mostly focuses on middle/upper income people (this is key, not Dave Ramsey shaming poor people shit) and it's wild how often people don't grasp they are the problem.
I also go back to Alice Miller a lot, and ponder the emphasis on childhood "discipline" (read: punishment) and obedience among the biggest voting bloc for Trump, the white evangelicals.
Targets are selected at a systemic level and that is sociology. But also, abused children grow up and hit down.
There is special bigoted magical thinking tied with racism and entitlement at the core of the "American Dream": If you're not living the dream, if must be *their* fault.
I assume it's based on classism as a tool of political power, filtered thru US's history of chattel slavery and systemic racism.
