Maybe I am mistaken, but wouldn't it be cheaper for the government to just make sure that they treat their prisoners in a respectable fashion than it would be to actually run your own prisons?

Running a prison isn't quite the same as running (say) a sweet shop.
Ah, but are you sure that is the right metaphor, perhaps you were trying to say, sweat shop, perchance?
