"Which brings me to the third myth: that health reform is fiscally irresponsible. How can people say this given Congressional Budget Office predictions — which, as I've already argued, are probably too pessimistic — that reform would actually reduce the deficit? Critics argue that we should ignore what's actually in the legislation; when cost control actually starts to bite on Medicare, they insist, Congress will back down.

But this isn't an argument against Obamacare, it's a declaration that we can't control Medicare costs no matter what. And it also flies in the face of history: contrary to legend, past efforts to limit Medicare spending have in fact "stuck," rather than being withdrawn in the face of political pressure.

So what's the reality of the proposed reform? Compared with the Platonic ideal of reform, Obamacare comes up short. If the votes were there, I would much prefer to see Medicare for all.

For a real piece of passable legislation, however, it looks very good. It wouldn't transform our health care system; in fact, Americans whose jobs come with health coverage would see little effect. But it would make a huge difference to the less fortunate among us, even as it would do more to control costs than anything we've done before.

This is a reasonable, responsible plan. Don't let anyone tell you otherwise. "
