A massive new penal system has emerged in the past few decades - a penal system unprecedented in world history. It is a system driven almost entirely by race and class.

Certainly youth of color, particularly those in ghetto communities, find themselves born into the cage. They are born into a community in which the rules, laws, policies, structures of their lives virtually guarantee that they will remain trapped for life. It begins at a very early age when their parents themselves are either behind bars or locked in a permanent second-class status and cannot afford them the opportunities they otherwise could.

Most Americans violate drug laws in their lifetime, but the enemy in this war has been racially defined. Not by accident, the drug war has been waged almost exclusively in poor communities of color, even though studies have consistently shown - for decades - the people of color are no more likely to use or sell illegal drugs than whites.

I do believe that something akin to a racial caste system is alive and well in America.

I think it's critically important that the people who have been most harmed by mass incarceration, by mass deportation, by neoliberalism, by all of it, not only have a voice in crafting these platforms but emerge and are supported as real leaders in these movements.

About 70% of those released from prison return within a few years, and the majority of those who return in some states do so in a matter of months because the challenges associated with mere survival on the outside are so immense.

If the drug war was waged in those communities it would spark such outrage that the war would end overnight. This literal war is waged in segregated, impoverished communities defined largely by race, and the targets are the most vulnerable, least powerful people in our society.
