older, less healthy workers to cover. That coverage will necessarily be more expensive, which will encourage more and more employers to give up on the idea of providing coverage at all.

The upshot is that many more Americans — millions more — will find themselves on their own in the bewildering and often treacherous health insurance marketplace. As Senator McCain has said: "I believe the key to real reform is to restore control over our health care system to the patients themselves."

Yet another radical element of McCain's plan is his proposal to undermine state health insurance regulations by allowing consumers to buy insurance from sellers anywhere in the country. So a requirement in one state that insurers cover, for example, vaccinations, or annual physicals, or breast examinations, would essentially be meaningless.

In a refrain we've heard many times in recent years, Mr. McCain said he is committed to ridding the market of these "needless and costly" insurance regulations.

This entire McCain health insurance transformation is right out of the right-wing Republicans' ideological playbook: fewer regulations; let the market decide; and send unsophisticated consumers into the crucible alone.

You would think that with some of the most venerable houses on Wall Street crumbling like sand castles right before our eyes, we'd be a little wary about spreading this toxic formula even further into the health care system.

But we're not even paying much attention.
