If you include economic causes, you might need to include the excess mortality of systematically impoverished communities in western nations — and I don’t just mean “PoC in the USA”, as I can point to a UK study claiming the government’s austerity policies since 2010 have caused 120,000 excess deaths: https://www.bmj.com/company/newsroom/health-and-social-care-...

Why control what people do when you can control what people want to do?
