I have yet to devote sufficient time to educate myself on many of the issues surrounding the threat of government run health care, its rising costs in general, the “millions” of uninsured and the moral implications thereof in a rich nation.
Megan McCardle has a good post on the culture surrounding health care in the US. I know that if someone I cared about got sick, I would tap into my entire network and scour the internet evaluating every option available. I know of at least one person who got lucky by stumbling upon a clinical trial for a cancer treatment that has extended his life. The transparency that comes with our democracy is going to make this nearly impossible for a bureaucracy to make these choices without incredible political backlash. Think about how we all feel about our current private health care providers. Now add electoral politics to what you are feeling.
I am sure this is much I have not considered. I am positive that there is no easy answer though.
