I'm coming back to the theme of a looming financial crash, because I really think we're on the cusp.
One of the things that sometimes gets lost, wrt financing the debt, is that until very recently the debt that was rolling over had been borrowed at pre-ZIRP rates and was being replaced with very low interest rate debt. That meant a much higher total debt load could be carried at the same cost. Now, that old debt is getting rolled over at similar rates to what it was borrowed at, so there aren't any savings that can cover the new debt being accrued.
