While the United States remains mired in the deepest slump since the Great Depression, President Barack Obama is touting a modest improvement in employment over the past several months to boost his electoral prospects in November.

The three-month period from December through February has, according to the Labor Department, seen a net gain of 744,000 jobs, the largest for any three-month stretch since 2006. The official jobless rate has fallen from 9.1 percent in September to 8.3 percent in February.

It is necessary to place these gains within the context of the catastrophic collapse in employment that followed the Wall Street crash of 2008, which has left the US economy with 5 million fewer jobs than at the official start of the recession in December 2007. At the height of the crash, US businesses were cutting more than 744,000 jobs every month.
