Obstacles to employment are a problem. They impede social mobility, disproportionately harm society’s most vulnerable citizens, and hinder the larger economy. That is why efforts to remove such barriers have become a bipartisan cause. It’s why more than two dozen states now ban public employers (and sometimes even private ones) from inquiring about applicants’ criminal history, due to concerns that capable job candidates will be turned away or otherwise deterred. A number of states and locales are going further: New York City, for example, prohibits public employers from asking about applicants’ prior-earnings history; in 2016, Massachusetts became the first state to prohibit the practice for all employers.
