The jobless rate may have hit the level signaling full employment, but the economy is still millions of jobs short of a complete recovery from the Great Recession, according to a new study. The economy needs to create 6.4 million more jobs, about half for college-educated workers, to combat flat wages and a slack labor market that continue to plague it, according to a report from the Georgetown University Center on Education and the Workforce. “We’ve been adding jobs for six years, but the economy is still fragile,” said report author Anthony Carnevale.
