It sure seems like some people on this page are very much in favor of people who've committed crimes going hungry, even after they serve their sentences.
Idiomatically, I'm also in favor of every person, inside or outside of prison, getting the education they need in a trade that suits them.
Our society would benefit enormously, far beyond the cost of providing the education. So again, free lunches for all! Literally and metaphorically!
Yes, nobody should go hungry. Not in prison, not out of prison, nowhere.
