The Bush Budget Deficit Death Spiral
Lenders talk about a "debtor's death spiral." It occurs when borrowers get so far in over their heads they begin borrowing money just to cover the interest payments on past borrowings. The borrowers have to do this to keep the lending flowing but they can no longer plausibly pay down the principal. As new debt compounds on old, bankruptcy becomes imminent. Further lending is foolhardy. Foreclosure is only a matter of time.
