The Congressional Budget Office (CBO) already found the minimum wage increase President Barack Obama touted to Democratic governors Friday is likely to reduce employment.

Could it also have a disparate impact on minority groups?

Al Sharpton doesn’t think so. When he appeared at the White House earlier this week, he said,  “What must be weighed in any analysis, CBO and others, is that blacks suffer disproportionately from having to do work and not get the kind of wages that we need.”

Some economists think otherwise. They point to a 2011 Employment Policies Institute study concluding that past minimum wages have hurt black employment prospects the most.
