Paul Krugman Follow-Up at the Economist's View

From his follow-up there:

I believe - and the evidence, I think, supports this belief - that the big problem is "adverse selection." An insurance plan offered to everyone at the same rate would be a great deal for relatively sick people, a poor deal for the healthy. So one of two things happens to private insurance. Either plans go into the "adverse selection death spiral," as sick people flock in, driving up rates, driving out more healthy people, and so on. Or insurance companies spend a lot of the money they receive in premiums screening out "high-risk" clients, so that the system has huge overhead and the neediest cases are excluded.

The clean solution to this problem is for the government to provide insurance to everyone. Other rich countries do that. So do we, for older Americans, veterans, and others. Actually, government health insurance is already bigger in America, in dollar terms, than private insurance - it covers fewer people, but that's because the elderly, who cost more, are handled by the government.
