Absolutely, there's a reason people become career criminals. If we remove any opportunities to make money legally people will turn back to criminal ways to make money.

Prison isn't punishment that you "pay for"with time. Its a center for rehabilitation.

If you did the crime and were rehabilitated with time*, theres no reason you shouldn't be reintegrated into society free-and-clear*

As a financial institute, I'm not hiring someone convicted of fraud whether they served the time or not. That's just goofy. I'm not the one that's going to give someone that's already proven themselves malicious to hurt my customers.

By all means, go become an engineer or an architect. And after sufficient time goes by as a functioning member of society, apply for a pardon and get the record expunged. But the record is there for a good reason.
