This thread offers us an opportunity to understand why it does. Look at how many comments ordain the practice out of a callous disregard for those who incur the unfortunate label of "criminal." A criminal can be anything from a man who kills a child to a homeless man who was caught sleeping in the wrong place too many times, but this nuance doesn't seem to factor into the thinking of supporters of modern day slavery.

I've also noticed that people carry with them a suppressed anger that comes from being forced to follow the law and perform all the duties of a functional citizen. Anyone who breaks the law is not enduring the burdens of citizenship as they are, and so the "criminal" becomes a virtuous outlet for their suppressed rage. The criminal thus becomes a kind of scapegoat.
