Since 2008, we've heard several times that recovery has begun; but events around the world--European debt crises, Middle East revolutions, the earthquake, tsunami and meltdown in Japan, and now political infighting in Washington--keep intervening to strangle it.

So it seems like a bad time for Congressional Republicans to point a gun at the national credit rating and scream, "One step and I'll shoot!" If the debt limit increase is snarled, confidence in our bonds may crater even if Treasury is able to find a temporary way to maintain the interest payments. If the world no longer feels solid about U.S. debt, the consequences could be as bad as 1932-33.

That's where the good old text of the Constitution comes in--the actual text, not the mythical snippets that many Americans misremember from eighth-grade civics, and not the truncated redaction that too many lawyers, alas, learn in their first-year Con Law class.

Section Four of the Fourteenth Amendment states, at its outset, that "[t]he validity of the public debt of the United States, authorized by law, including debts incurred for payment of pensions and bounties for services in suppressing insurrection or rebellion, shall not be questioned." This section was inserted into the Amendment because of a very real concern that Southern political leaders, and their Northern allies, would gain the upper hand in Congress in the 1866 or 1868 elections and vote to repudiate the national debt.

The Lincoln administration had borrowed freely to finance the war machine. As Reconstruction dawned, white Southerners complained bitterly that they would now be taxed to repay the funds that had been borrowed to defeat their cause. "What, ruin us, and then make us help pay the cost of our own whipping?" one asked a Northern journalist in 1865. "I reckon not."

Southerners were used to having their way in Congress--they had dominated the institution from 1787 until secession in 1861--and many believed that when their representatives arrived in House and Senate, they would be able to tear up the nation's IOUs.

Section Four was the response; its language is extraordinary. First, it does not simply say that the national debt must be paid; it says that its "validity ... shall not be questioned." Only one other section of the Constitution--the Thirteenth Amendment's proclamation that "[n]either slavery nor involuntary servitude ... shall exist within the United States, or any place subject to their jurisdiction"--is as unqualified and sweeping.

Second, it suggests a broad definition of the national debt: "...including debts incurred for payment of pensions and bounties for services in suppressing insurrection or rebellion."

From this language, it's not hard to argue that the Constitution places both payments on the debt and payments owed to groups like Social Security recipients--pensioners, that is--above the vagaries of Congressional politics. These debts have to be paid, the argument would be, in full, on time, without question. If Congress won't pay them, then the executive must.
