The U.S. economy added 431,000 jobs in May, but just 41,000 in the private sector. 411,000 jobs are for U.S. census workers, who will only have jobs for a few months. Should we cheer positive numbers or be concerned that the private sector gains are far less than last month? How does the oil spill make these numbers even more sobering? What is the real unemployment number when factoring in those who have given up the job search or are forced to take part-time work? Why are private employers reluctant to hire? What would give them more incentive? We Ask Diana Furchtgott-Roth, chief economist for the Department of Labor under President George W. Bush.
