People who are not insured dump their costs on the rest of us.
So that leaves four choices:
> bill these people
> deny care to these people
> force insurance upon them (obamacare)
> encourage getting coverage in the market.
I want costs to be as low as possible so that people can actually choose to insure themselves. As for those below the poverty line, some sort of catastrophic insurance plan would defray costs; anything short of that should require billing of the individuals. If all of that is refused, then deny care.
