Fine rollup, GH.

What's sad, is to go the other way, and figure out the time required, per taxpaying citizen, to bring the debt incurred to zero... "paid off".

Without doing the long division necessary, I'll estimate: 25 years.

So in 2034, when I'm dead, and my now-6 year old grandson is 31, his country will be debt-free if we don't try to borrow more money in the next 25 years (what are the odds of that?).
