Since there's already Medicaid for the poor and no hospitals deny care now... your statement would appear to be incorrect.
I don't mind funding a worst-case-scenario safety net for the most vulnerable in the society. I don't mind some serious legislation aimed at fixing the real problems with healthcare in this country. The law passed by the Democrats in 2009 was a useless counterproductive disaster.
I work at an urgent care. We routinely turn away people who are uninsured or have Medi-Cal (California medicaid) AND are unwilling to an upfront fee for the evaluation. So we see the uninsured but only if they pay. I see no difference in the chief complaints, but the uninsured generally wait quite a bit longer, and therefore often need not 5 times as much care, but 100 times as much.
"Individuals who do not have health care or can not pay for it should be denied treatment".
That's what happens when you leave it up to free markets.
