The prison part is the slavery, the digging the whole is the labor. As you have pointed out, there's an odd pearl clutching among a lot of people on the matter. I think those who argue of the negative incentives it creates are right, but too many appeals to emotion over the term slavery. The reason the 13th amendment included the crime provision is so that we can continue to imprison people, any work they do or don't do is secondary to the loss of rights.
