By some estimates, income and wealth inequality are near their highest levels in the past hundred years, much higher than the average during that time span and probably higher than for much of American history before then.

The bottom line for housing is that the concerns we used to hear about the possibility of a devastating collapse—one that might be big enough to cause a recession in the U.S. economy—while not fully allayed have diminished. Moreover, while the future for housing activity remains uncertain, I think there is a reasonable chance that housing is in the process of stabilizing, which would mean that it would put a considerably smaller drag on the economy going forward.

For my own part, I did not see and did not appreciate what the risks were with securitization, the credit ratings agencies, the shadow banking system, the S.I.V.’s — I didn’t see any of that coming until it happened.

The average net worth of the lower half of the distribution, representing 62 million households, was $11,000 in 2013. About one-fourth of these families reported zero wealth or negative net worth, and a significant fraction of those said they were "underwater" on their home mortgages, owing more than the value of the home. This $11,000 average is 50 percent lower than the average wealth of the lower half of families in 1989, adjusted for inflation.

Will capitalist economies operate at full employment in the absence of routine intervention? Certainly not.
