Charles Smith at Of Two Minds explains how ever-increasing fixed costs: taxes, pension funds, health insurance &c., can turn what would otherwise be a recession into a catastrophic depression:

Here's the difference between a recession and a depression: you can't get blood from a stone, or make an insolvent entity solvent with more debt. Losses will have to taken, and nose-bleed fixed-costs will have to be slashed; reality will eventually have to be dealt with.

But everyone will resist this process because high fixed costs are the gravy train everyone depends on. Slashing fixed costs destroys the income needed to support asset valuations which are the collateral for the stupendous mountains of debt that define the U.S. economy. Once that debt is written down, the entire financial system collapses.
