I would hope that society would rather me work and pay taxes, offsetting the cost of keeping me here, and giving me hope, responsibilities, discipline and a reason to continue making good life decisions when I am released.
95+% of those incarcerated are getting released one day.. People who have nothing to lose, no sense of self worth, or any feelings of identity with the rest of society are likely not people you want moving in next door to you.
I might be in prison but I lead a team of developers and contribute to open source regularly. I found my passion and I am now a contributing, tax paying member of society and no longer identify with the prison subculture at all.
It's difficult to see how this outcome could be viewed in any way as negative. I know that I made poor decisions, and I am not proud of them, or who I was at the time at all. I wanted to change my life and Maine gave me an opportunity to do that through hard work and I am extremely grateful for it.
