Anyone can go to the emergency room and get treatment...

Whoo, Boy, Carlin! LOL!! I'll leave this for some of the 'Catters I know who work in health services to deal with at length, but suggest as an experiment you go to an E.R. in any fairly large city, tell them you have no health insurance, and report back on the outcome.(We won't talk about rural America, where many folks can't get TO the E.R. 60 or 100 miles away) Try asking them about dental care. Or a mammogram. Or prenatal care. Or preventative medicine. Or how to pay for any prescriptions they might give you, if you're VERY fortunate.

This isn't anything CLOSE to health care.
