trillion + national debt
Here's a link from the first sight I hit that goes back to '99

The problem is that the debt is meaningless. The debt is a product of taxes and spending. When taxes are less than spending, the debt goes up. When taxes are more, the debt goes down. But, the tax rate isn't as meaningful as you think. If you raise taxes so that the debt doesn't go up, you have less money now, because taxes went up. If you don't raise taxes, you have more money now, but you owe in the future.
The point being, it is the spending that matters. Whether it is paid for now or later doesn't matter all that much.
Sounds like the Concord Coalition.
