David Leonhardt in the New York Times Magazine:
As Barack Obama prepares to accept the Democratic nomination this week, it is clear that the economic policies of the next president are going to be hugely important. Ever since Wall Street bankers were called back from their vacations last summer to deal with the convulsions in the mortgage market, the economy has been lurching from one crisis to the next. The International Monetary Fund has described the situation as “the largest financial shock since the Great Depression.” The details are too technical for most of us to understand. (They’re too technical for many bankers to understand, which is part of the problem.) But the root cause is simple enough. In some fundamental ways, the American economy has stopped working.
The fact that the economy grows — that it produces more goods and services one year than it did in the previous one — no longer ensures that most families will benefit from its growth. For the first time on record, an economic expansion seems to have ended without family income having risen substantially. Most families are still making less, after accounting for inflation, than they were in 2000. For these workers, roughly the bottom 60 percent of the income ladder, economic growth has become a theoretical concept rather than the wellspring of better medical care, a new car, a nicer house — a better life than their parents had.
