US credit downgrade?

Given all of the debt that has to be serviced, will this make paying interest on it more expensive.

When I first moved to NYC, Mayor Lindsey had finished his binge spending on social "investments" sending debt off the scale with promises of a shining future. The shining future didn't happen to pump up city revenue. In fact, the opposite happened. Revenue fell and debt service shot up to the point that neglect of basic physical maintenance was the only "solution."

Of course, NYC couldn't print its own money.
