US healthcare is pretty atrocious for the $$$ they bring in.
The system can be better but lots of rich people would lose a lot of money and a lot more people would be out of work.
Politicians are not signing up to lose their next election either.
Any radical change will come from a 1 party rule with super majorities in House and Senate. That is how Obamacare was passed. And I don't think its moved the needle much other than get people insurance who otherwise couldn't get it.
