I DO understand your objection, but in fact we have "socialized" medicine to the extend anyone can go to ER and ultimately find a hospital that PROBABLY will treat them. However, it is terribly organized, is a hodgepodge overall, and the whole system of healthcare is a mess - and it's not just government and insurance companies, but special interests, the AMA, drug companies, FDA etc, etc.
Society - right or wrong - is NOT going to allow poor people dying on the front yards of hospitals. SO the question is what then?
A large percentage of people cannot afford their healthcare, nor could afford the costs of insurance - noting that insurance doesn't provide healthcare and is just a Las Vegas middleman. In short, I think it isn't a question of "if" we have "socialized medicine." We already did and already do. The question is what form of it?
The reason I don't think it works on a local or state level as there it would be in the economic incentives to try to get indigent healthcare done in another city or state.
