We need to replace it, but not with universal healthcare, which had fail in every country that has tried it. What universal healthcare really means is that you can get on a list for heath care and if you don't die they will treat you sooner or later.
What's sad is there was a plan that would have offered coverage to anyone who wanted it, the policy was a cost plus, that is insurance companies only got paid if they approved procedures, so they would be enticed to find way to cover people, no to deny them. Now to entice people to get coverage, hospital would be allowed to deny treatment to those who can't pay. We would also have a program to help the poor pay for coverage. A Win, win, you don't have to have coverage, but you can't get treatment unless you pay, so the rest of us won't get stuck with the bill.
