The wise minds at Moody’s Investors Service finally acknowledged last week what the other two main credit rating agencies did years ago: America has a debt problem.

Now it’s time for America to recognize that solving its debt problem will require addressing another hard truth: Americans have a retirement problem — specifically, they retire too soon.

Despite reports that Moody’s decision is related to the fiscal impact of the $3.7 trillion tax legislation the House is currently debating, that bill is just the proverbial rearranging of deck chairs on the Titanic. The biggest source of America’s long-term debt problem, which is not even included in the 10-year budget projections, is unfunded entitlements, largely Social Security and Medicare.
