Bloomberg economist Joseph Brusuelas talks about the June U.S. employment report released today, challenges facing the labor force and U.S. economic policy.   Employers added 18,000 workers last month, following a 25,000 gain in May that was less than half the rise initially estimated, Labor Department figures showed. The unemployment rate unexpectedly climbed to 9.2 percent, the highest level this year. Brusuelas speaks with Lisa Murphy on Bloomberg Television’s "Fast Forward."
