I recommend David Broder's editorial in the Washington Post, Will the Current Proposals Fix Health Care?.
The problem isn't that the first-cut proposals coming out of the Congressional committees aren't perfect. A first-cut is just that - a first try. The problem is that the president and the Democratic Congress are rushing to get a bill through before the administration's honeymoon is over, so we may get stuck with the first-cut -- yet another hastily-assembled and poorly-thought-out bill just like the stimulus package.
Health care certainly needs fixing, but if all we get is a bigger deficit and higher taxes, and yet no fix to the fundamental health care problems, then in a year or two we will be far worse off than we are now.
