"... [I]it's as if you put charges on your credit card, then decide later whether you're going to pay for them," The Atlantic's James Fallows told NPR's Guy Raz yesterday.
This is money past Congresses and this Congress, too, have already voted to spend....
... [R]atings agencies have already said that even though, of course, people know that the U.S. government is not going to finally renege on its obligations, the interest rate that the U.S. has to pay for its Treasury notes and other debt will probably go up if there is this default because it's always been defined as the most riskless investment in the world.
And if and when that happens, essentially interest rates for everything else - for mortgages, for city governments, for state governments - they will all go up, too, because almost all of them are benchmarked to the supposedly riskless Treasury rate.
