he median American family — the exact middle between the wealthiest and the poorest — had the same amount of money in 2010 as it did in 1992, according to the Federal Reserve's Survey of Consumer Finance, an extensive and detailed look at American wealth undertaken every three years. While the latest data is 18 months old, it underscores the astonishing economic devastation wreaked by the Great Recession, which, beginning in 2007, swept away a chunk of the wealth accumulated since the early 1990s. (The Fed defines "wealth" as income plus assets — like homes, cars, and stocks — minus debts.) Here, a numerical look at the average family's struggles:
