I'll pay you $150k to watch over 10 children for 7 hours a day or one violent and mentally ill murderer 24/7. What do choose?
To me, when I see 150k, I don’t see a cost — I see a facade.
Homicide is not insignificant for state prisons (around 15%). Violent crime is over 50%. And mental illness is a huge problem in prisons. Would you care to take the chance of who you get in this?

[EDIT] and that's beside the fact that it's irrelevant if you're looking at "what could we have bought for this instead". No bearing whatsoever.
So, it's both "so expensive" and there was "no suggestion that it ought to be cheaper?" Cool. So, what in his inkblot of a post did you read as the solution to keeping violent criminals from subjecting society to their violence?
