For years, opponents of Social Security reform have told us that there is no need to rush into changing the program because, after all, Social Security is running a surplus today. Well, according to a new report by the Congressional Budget Office, not so much.

CBO reports that the Social Security surplus, originally expected to be $80-90 billion this year and next will shrink to $16 billion this year and just $3 billion next year (essentially a rounding error) as a result of the recession and rising unemployment. And those estimates may be far too optimistic. In February of this year, for example, Social Security actually ran a deficit—spending more than it took in through taxes and interest combined.

And, while CBO expects a return to modest surpluses after 2010, as the recession ends and unemployment falls, that is betting on the success of the unproven Obama economic program. If unemployment stays at current levels, Social Security will begin running permanent cash flow deficits in 2011 (eight years earlier than previously predicted).

Opponents of personal accounts have pointed out recent declines in the stock market as a reason why private investment should no longer be considered an option for Social Security reform. The evidence suggests that, even with recent market declines, private investment would still produce higher returns than Social Security. The new surplus numbers provide yet another lesson: if the economy is in such a mess that it hurts private investment, traditional Social Security isn’t going to be in any better shape.

The case for personal accounts remains as strong as ever.
