I could put a long list of non-government health care concepts here from people who have thought about this for years. I could point out that 8 out of 10 Americans are just fine with what they've got. We could rehash again the problems in places like Canada, which involve more than just the old "people coming to America for health care" meme. We could go over where innovation in health care really comes from.
I've done all these things in the past, and in great detail.
But if someone asks me who should be driving the bus on the mountain road, "not the blind guy" is an informative answer, and is enough of a response for those who are not only yelling for the blind guy to be the driver, but have heard all of the above and ignored it.
