If President Barack Obama had made the passage of such a law and the establishment of such an agency the centerpiece of “health-care reform,” he would be in a lot better shape politically than he is. But for whatever reason─perhaps he doesn’t want to come off as a “Big Government” man─he hasn’t really done so. At least he hasn’t explained his proposals in this way, or explained it clearly and compellingly. Which is puzzling, since this is a stirring theme, and one in the American grain, stretching at least as far back as Teddy Roosevelt and the Trust Busters of a century ago.
