Krugman reminds us of just how stupid and expensive our health care system. I tend to side with him that constructing elaborate and insurance-industry-plans is likely a sucker's game, but I think what's most important is convincing enough politicians that universal health care is something they should get behind. The details, while important, are something we can fight about.
Krugman leaves out one thing - not only do we spend more than everyone in the world on health care, our government spends more than other governments spend on health care.
