Excellent idea.  Maybe a lot cheaper to administer than what we have.  A similar idea was proposed back when Congress was considering a national health plan.  The Republicans didn't like it, nor any other plan which did not allow insurance companies to profit hugely.  'Obamacare' was the compromise the GOP allowed it to pass.  Now the insurance companies whine (by their own estimate) they aren't getting enough money and must keep raising premiums.
