Where I'm from in the US..You get time off your sentence, a better chance at parole, and a small check at the end of month depending on what you were doing..if you are lucky, you get to be outside on a golf course or a dog pound..I think mine was around 67 bucks a month..It's a no brainer for most people unless you just like sitting around watching TV and listening to people bicker/fight/od all day. Yoda, you think you are?
