They use court appointed slaves to run a religious institution. If you get a drug charge the judge has the option to give you community service vs jail. This is usually at their discretion. So what we end up having is people with drug problems becoming constitutionally sanctioned slaves working for a religious institution of a judges choice. The drug issue isn't fixed, the religious right get slaves, and the religious right gets more money to fund their agendas. It always magically comes down to slavery, folks. The 13th amendment allows for slavery under these circumstances. So as long as that exists, slavery will exist, and the prison industrial complex will exist.
