U.S. Homeowners Are Repeating Their Mistakes

If there’s one thing Americans should have learned from the recession, it’s the importance of diversifying risk. Middle-class households had too much of their net worth tied up in their homes and were too exposed to stocks through 401(k)s and other investments.

Despite the hit many Americans took, there’s little sign they’ve changed their dependence on homes as the mainstay of their wealth. Last year, Christian Weller, a professor at the University of Massachusetts, looked at Federal Reserve data for households run by those over 50. The number of families with what Weller calls “very high risk exposure”—a low wealth-to-income ratio, more than three-quarters of their assets in housing or stocks, and debt greater than a quarter of their assets—had almost doubled between 1989 and 2010, to 18 percent. That number didn’t decline during the deleveraging years from 2007 to 2010; its growth just slowed to a crawl.
