Look at how many people will lose their jobs if this shuts down. The people who support this are often just happy to see minorities and poor people get fucked if it means their stupid brother in law stays on at the local prison. They view these people as human waste, so they don't care how much they get hurt, as long as their people are getting something out of it. Trying to stop this means figuring out how to unfuck these people's mentality. That is even harder than stopping drugs.
