I don't think we have a shortage of ideas for accomplishing this. What we have is a shortage of willpower.

All it takes is one asshole being put into a rehabilitation program[1], or one sufficiently high-profile crime committed by someone in a program/on parole, for half the country to sour about prison reform.

It's easier to send the bad people to the gulag, and forget about them. Treating crime in a constructive way is expensive, and doesn't work 100% of the time, so why bother?
