Care to provide the source for the $0.13/hr? Inmates are paid as little as $1/hr and as much as minimum wage with the lowest hourly rate going to the inmate firefighters due to how the budget is set by the forestry service. The last time I saw the $0.13/hr number trotted out it was also skewed by jobs that paid per piece and not per hour. Inmates that have to pay restitution pay about 5% of their wages, and each working inmate pays deductions for room and board as dictated by the state legislature. I've also seen those with an agenda perform hourly wage calculations on the inmate pay _after_ deductions. If you've got a reputable source that can show otherwise I'd love to see it. I'll also note that I'm related to a recently retired department of corrections officer and have used other prison industries services and am familiar with how it works and what the wages are from dealing with the services and the personell running parts of prison industries in Nevada.

That's slave labor.
