Nothing:  Hey, great point....I bet there are millions of folks committing crimes just so they can go to prison, serve a term, then try to reintegrate into society carrying the brand of "ex-con."  Sure looks like fun to me.   If you're really interested in the "crime doesn't pay" question, let's talk about White Collar Crime sometime.....that's where the "real money" is made and those are the folks least likely to be held accountable and least likely to serve "hard time."
