Anecdotal - A friend of mine decided to go without health insurance this year and then tore her ACL. So guess who is walking around with a torn ACL until next year because she simply can't afford the surgery...
The US healthcare system is rotten to the core but the populous refuses to educate themselves and keeps voting for losers that won't do anything to fix the system - so we all suffer. Republicans have been promising an alternative to the ACA (for some reason) for over 10 years now and have yet to produce anything - They are just interested in tearing down any progress and not offering fixes to current problems... but thanks to voter education and gerrymandering Republicans are able to keep their vulture capitalism ideals afloat. That's not even mentioning establishment Democrats that don't do much when they have the chance.
