Well, we're either going to have a flat out economic collapse, which will result in drastic unemployment and no standard of living for potential decades, or spending on a grand scale in this country will need to be slowed down to keep up with and pay for the debt, which also equals unemployment.
Or we're somehow going to have to find a way to get 10% GDP growth for the next several decades.
We're at the verge of Zimbabwe economics, but at least we've become that way with a high standard of living to begin with.
