Health care is actually hugely underestimated, here. Health costs have been going up decade over decade and people’s health problems have been stacking up. While in the '70s and '80s people could get treatment, someone born in those years started out with the ability to get medical care but has increasingly lost access as they’ve gone through their lives.
Those people are getting older, now, and it’s getting to the point where they can’t just ignore the stuff they can’t afford. Conditions that would have been easy to treat (but often rare/expensive) are becoming chronic, fatal, or debilitating.
Life expectancy is starting to drop and while that drop is largely due to COVID (which, by itself, is an insane thing) it’s also a warning sign about what’s to come.
