The economy was very sick before the crisis; the housing bubble merely papered over its weaknesses. Without bubble-supported consumption, there would have been a massive shortfall in aggregate demand. Instead, the personal saving rate plunged to 1%, and the bottom 80% of Americans were spending, every year, roughly 110% of their income. Even if the financial sector were fully repaired, and even if these profligate Americans hadn’t learned a lesson about the importance of saving, their consumption would be limited to 100% of their income. So anyone who talks about the consumer “coming back” – even after deleveraging – is living in a fantasy world.
