There is a see-saw. The more insurance covers, the more it costs. So there will either be a healthcare cost "problem" (when insurance covers not enough, we are here) or a health insurance cost "problem" (this is what it was like prior to the ACA, everything was covered but many couldn't afford it).
Getting everyone on insurance got rid of the people that would go to the hospital without it an eventual die in it. The hospitals would have to eat the costs and pass that on to everyone else. ACA use to have a lot of stuff that all health insurance HAD TO cover, but the GOP has been slowly eating away at that list.
Shhhhh.... let it pass. The generation after D.A.R.E. made marijuana legal. What do you think kids will do when teachers start saying socialism is bad and that they should stay away from it?
