>Sure you can. Interest.
Ah, so interest doesn't count as spending because it's not being paid off? The US economy is doing great because the government has reached the point where it's only running up $175,000,000,000 in unpaid interest every year? Wow, I must run out and celebrate; let's party in the streets!
Somehow I don't think I'd be doing too well if I was accumulating unpaid interest every year equal to more than a tenth of my income.
