It's not easy:
We ran an audit experiment that sent trained testers to apply for more than 1,000 entry-level jobs throughout New York City. The fake job applicants were dressed similarly, gave similar answers, and provided résumés with identical education and work experience. At each job interview, however, one randomly chosen tester would tick the application box indicating a criminal record and submit a résumé that mentioned a prison and provided a parole officer as a reference.
White testers who were assigned a criminal record received call-backs or job offers from employers only half as often as testers with clean records. For African Americans, a criminal record reduced employment opportunities by two-thirds. Labor force data from the National Longitudinal Survey of Youth paint a similar picture of incarceration’s negative effects: Wages fall by about 15 percent after prison, yearly earnings are reduced by about 40 percent, and the pay of former prisoners (unlike compensation for the rest of the labor force) remains stagnant as they get older.
