"I suspect you seriously overestimate the market value of that labor (or understimate prison costs)."
Regardless, I don't suspect your motivation, it's obvious. At least I'm trying to offer opinions to curb problems unlike you, offering no solutions, just sitting there nit picking posters.
Some problems have no "solutions" (other than changing one heart at a time); what I offer is the sound conservative advice to not create more problems than we solve just to be 'doing something.'
