If beer companies compete that is good for beer drinkers and does not affect those who do not drink beer. But in the case of health services it is obvious that many of the cost reductions negotiated by the competing insurance companies, end up expected to be recovered from those uninsured.
If it was in my hand (perhaps it's good that’s not the case) I would put up a prohibition to charge anyone more than 20% over the minimum price offered to any insurance company… and then take health reforms from there. Not doing so forces millions of uninsured who could pay reasonable fees to either swamp free service emergency rooms, or being financially abused.
Is not cost-discrimination against the uninsured a much worse discrimination than many of those other discriminations being protested so loudly?
