This much I have learned about debt after 40 years of writing and study: It is better not to incur it. Once it is incurred, it is better to pay it off. America, we have a problem.

We owe more than we can easily repay. We spend too much and borrow too much. Worse, we promise too much. We conjure dollar bills by the trillions–pull them right out of thin air. I won't insist that this can't go on, because it has. I only say that it will eventually stop.

I don't know the date, but I believe that I know the reason. It will stop when the world loses confidence in the dollars we owe. Come that moment of truth, the nation will resemble Chicago, a once prosperous polity now trying to persuade its once trusting creditors that it is actually solvent.
