Around 8.4 million jobs have been lost since December 2007. According to economists surveyed by the Wall Street Journal, around a quarter of the lost jobs are gone for good. The survey comes as the White House released an economic forecast projecting job growth this year will be too low to significantly address unemployment. The projection says employers will add just 95,000 jobs per month, a number just below what economists say is needed just to keep up with population growth.
