The story of America’s recovery from the recession has been one of dashed hopes. In early 2010, and again early last year, the economy looked as if it might be starting to grow under its own power, only to slow markedly in the months that followed. So what should we make of the current signs of rebound? The employment report for February, which came out last week, was solid, meaning that businesses have created more than two hundred thousand jobs a month for three months in a row. Economic data show that the economy, and real incomes, grew at a fine clip at the end of 2011. And unemployment, while still painfully high, has fallen a full two points from its peak. Bitter experience might suggest that we regard these numbers with a jaundiced eye. But there are at least a couple of reasons to think that, this time, we aren’t looking at a false spring.
