What's wrong with a two-tier system - free basic coverage, rest paid? Reference: Germany. There are all shades between the current healthcare system in the US and the completely free, cover everything including condoms and dildos, system introduced by the Sanders nut and now uniting all radical lefties. As long as that's the only alternative, most people would prefer the current system.
I want dildo coverage. I was visiting UK and walked into a clinic and got best medical services of my life. US has a lot of room to improve but we gotta get over doctors need to be smartest people in room. They don't.
