You and I, the tax payers, are who ultimately pay for lodging for prisoners. It makes much more sense to me for the person who committed the crime to bear this cost (if possible).

The abuses of private prisons, etc is a tangential issue. As a high level, it's all still funded by taxpayer money.

But that is not the system we've set up. That also sets up a very scary system of indentured servanthood.

Why shouldn't you pay for food and lodging? You would outside of prison. Why should taxpayers foot the bill? Privatized prisons aside, because that is perverse and should be flat out illegal.
