What's really driving California's minimum wage hike?

A bill mandating a $15 per hour minimum wage was recently signed into law by California Gov. Jerry Brown.

California’s Restaurant trade association, the state’s Chamber of Commerce and Republicans warned that the law would hurt business and jobs. Not to worry, countered economists at U.C. Berkeley’s Labor Center, who claimed that in response to an increase in labor costs, businesses would simply become more efficient while the state would see no overall job losses.
