"If the prison system does it's job correctly, the accountant would not be released from jail if there was a good chance he'd commit the crime."
It is only the prison system's job to keep the prisoner behind bars for the length of his sentence. It is not up to the prison system to decide "if there was a good chance he'd commit the crime." Surely you're not talking about the parole mechanism to decide if the prisoner won't commit a crime again.
Bottom line: restricting employment opportunites creates recidivism.
