"Spending time in prison leads to increased criminal earnings," Hutcherson says. "On average, a person can make roughly $11,000 more [illegally] from spending time in prison versus a person who does not spend time in prison."
As to the process by which this happens, he says, "You come in [to prison]. You're 16, 17, 18 years old. You're looking around and you're thinking, 'Listen, I can learn from these seasoned veterans.' And that's exactly what you do. ... Basically, you are spending a lot of time around other criminals, seasoned veterans who know the lay of the land, and they can teach you the mechanisms — ways to get away with crime."
