First, we will rally (West Steps of the Capitol), with guest speakers who will discuss Mass Incarceration, the driving forces and solutions, then we will march to a highly visible McDonalds to protest their use of prison labor.

McDonald’s and many other corporations are investing in “zero-tolerance” school policies and other laws that makes it easier to target children for incarceration. Once in prison, McDonald’s and other corporations then rely on prison authorities and policies to exploit prison slave labor from those they have incarcerated.

McDonald’s uses prison slave labor to produce their uniforms, beef for patties, milk, bread, and plastic spoons. McDonald’s builds factories in prisons to exploit prison slave labor, but won’t build these same factories in communities where people in prison come from, where unemployment is high and jobs are needed.

Here is an interview done by KGNU with Melvin Ray, of Free Alabama Movement Ray discusses the economic drivers of Mass Incarceration and the private corporations that use prison labor to maximize profit gain at tax-payers expense, all the while investing in and lobbying for laws that keep people incarcerated longer. http://news.kgnu.org/2015/05/from-inside-alabamas-st-clair-correctional-facility-the-free-alabama-continues-to-blow-the-whistle-on-slave-labor/
