>> Things that people don’t do frequently never get fixed!

> Health care is something people use frequently, has broken processes, and high prices, and will seemingly never be fixed.

Your counter example doesn't work. The original claim was "things that people don't do frequently never get fixed", not "things that never get fixed are infrequently used by people".

I’d argue the majority of people don’t use it frequently.

Maybe not average aged working people, but everybody I know in the 60+ age group (mostly family) usually has regular interactions with the medical system, or at a rate far higher than 25-45 year olds.

And there's a lot of older people. As a cohort, there's only slightly fewer boomers than millennials.

Old people aren't necessarily the ones in a position to change the system. And the old people with power don't use the public system.
