To hell with S&P

More broadly, the rating agencies have never given us any reason to take their judgments about national solvency seriously. It’s true that defaulting nations were generally downgraded before the event.

And yet America does have big problems…

The truth is that as far as the straight economics goes, America’s long-run fiscal problems shouldn’t be all that hard to fix. It’s true that an aging population and rising health care costs will, under current policies, push spending up faster than tax receipts. But the United States has far higher health costs than any other advanced country, and very low taxes by international standards. If we could move even part way toward international norms on both these fronts, our budget problems would be solved.
