Even though I don't understand half of the items, the U.S. Debt Clock is fascinating. Because statistics without sources are useless, you can mouse over a number to see where it comes from. Amidst all the depressing figures, at least I can say that we're far better than average when it comes to personal debt, which amounts to over 56 thousand dollars per person! Fortunately, that figure includes mortgage debt, which can be less of a problem, though recent times have shown that's not always true.
On the other hand, the fact that our children and their families collectively own almost $860,000 of the national debt is more than a bit disconcerting. Those who are also Swiss get to add another $16,000 or so, with the consolation that the Swiss national debt is actually going down. You can see world debt clocks here.
From the main page you can also check out the state clocks. Or use their time machine to see how far we've come.
