While I don't think anyone should ever be denied necessary care, the manner in which it's being attempted is disgusting.
First, get rid of insurance companies totally. They do nothing that can't be done a different way while lowering costs. Second, heavily regulate business in one of two ways: either direct government regulation, or government supported competition for businesses which are exploiting the public. This is especially true of healthcare/pharmaceuticals. Stick or carrot, it matters not one whit to me, as long as the end result is fair treatment for all citizens. Third, overhaul the judicial system to punish frivolous lawsuits (like making lawyers equally responsible for their participation), protect good faith efforts by all (especially medical personnel), rewrite patent law to avoid hording or exploitation by companies, etc. Fourth, launch a program of social/cultural revision designed to get citizens back to savings (not investment) and living within their means (and not on credit). Fifth, create government guaranteed catastrophic medical loans to handle exceptional cases. Sixth, give serious examination to the 'drug mentality' in this country and unless overwhelming proof of its viability exists, combat it. Finally, adopt and promote a preventative care system which focuses on societal issues that cause the most problems (obesity, stds, pregnancy, drug/alcohol abuse, mental illness, etc).
