A 10% increase in wages for non-college educated men can result in a 10% to 20% reduction in crime—with concomitant savings in policing, prosecutorial, and incarceration expenses.
According to an article in The Atlantic, raising the minimum wage to $12.00 per hour by 2020 would reduce crime by 3% to 5% and yield "a societal benefit of $8 to $17 billion dollars."
The article draws an interesting conclusion that many incarcerated felons probably wouldn't be so if there'd been higher wages and more employment available at the time they committed their crimes.
But there are thousands of federal, state, and municipal laws regulating the hiring of persons with criminal records, which, in part, leads to a nationwide recidivism rate of 76.6%: if an ex-con cannot find a job then what options does he or she have?
This problem is exacerbated by the fact that about 60% of prisoners are functionally illiterate, unable to read above a 4th grade level.
