Considering how many other industrialized nations have it, we'd have to try incredibly hard to get it wrong. Plus, it's not like we can't make changes later.

Plus we already have Medicare, and do that pretty well.

One architectural difference is that the single-paying entity's job would be primarily to pay. The job of the many current entities is to not pay -- and to develop labyrinthine, nondeterministic, unknowable structures of great complexity to that specific end. Payments for care under our for-profit system are actually called "medical loss".

May be it doesn't. So should we just accept the Status quo ? I personally cannot and this issue is very important to me.
