It's impossible because you both political parties want exclusively mutual results
You can't have cheap insurance without making it mandatory since only the sick will get it
You can't have easily accessible insurance without forcing healthcare companies to comply with new regulations forcing them to increase costs
You can't have good insurance if you aren't willing to pay the market price which happens to be very inflated in the US
You cant lower costs in the US without having a more aggressive regulatory body which 50% of political bodies strongly oppose alongside lobbying efforts
Overall, it's a shitshow that will keep being patchworked every time the administration changes between parties.
