What are they waiting for?

General Motors lost $10.6 billion last year. It isn't all about selling cars in an increasingly competitve marketplace. The company spends $5.3 billion a year -- by far the most of any American company -- on health care for its employees, retirees and their dependents, a group that numbers about 1.1 million Americans, according to GM's chairman, Rick Wagoner.

One way for GM and other American corporations to reduce their health care costs would be to spread them more evenly in a national system. So why aren't American corporations clamoring for such a system to relieve them of some of these staggering costs?
