PRISON INDUSTRIES

...are like any other industry: they need to 'grow.' They sell the products that go into the building, maintaining & servicing of prisons. Everything that feeds, clothes, houses, cares for & educates prisoners are sold for profit. But profits require growth, and in prisons, that means more prisoners. So they give campaign $$$ to politicians & PACs, to pass new "tough" laws and lock more people up for longer.
