Where's the bottom?

What is the US National dept again? Something like 1.3 Trillion. What happens when we hit the bottom? Where in fact is the bottom? Will the deficit stop us from making changes? Right now the deficit is right around 74.6% of the GDP. In 1980 it was only 33.3%. If you have short-term memory you might say that the deficit is getting out of control but it isn't. In 1950 the deficit was 94.1% of the GDP. We should keep this in mind when we talk about how the administration is going to be forced to raise taxes on the middle class. They won't need to. We can handle it and the sky isn't going to fall.
