We're foolish if we think we're going to end mass incarceration unless we are willing to deal with the reality that huge percentages of poor people are going to remain jobless, locked out of the mainstream economy, unless and until they have a quality education that prepares them well for the new economy. There has got to be much more collaboration between the two movements and a greater appreciation for the work of the advocates in each community. It's got to be a movement that's about education, not incarceration - about jobs, not jails.

By waging the drug war and "getting tough" almost exclusively in the 'hood, we've managed to create a vast new racial undercaste in an astonishingly short period of time.

For the rest of their lives, [black men] can be denied the right to vote, automatically excluded from juries, and legally discriminated against in employment, housing, access to education and public benefits. So many of the old forms of discrimination that we supposedly left behind during the Jim Crow era are suddenly legal again once you've been branded a felon.

If you ask for good schools, you aren't likely to get them. If you ask for jobs or economic investment, you won't get that either. But what we have learned, is that the one thing that poor folks of color can ask for and get are Police & Prisons.

Arguably the most important parallel between mass incarceration and Jim Crow is that both have served to define the meaning and significance of race in America. Indeed, a primary function of any racial caste system is to define the meaning of race in its time. Slavery defined what it meant to be black (a slave), and Jim Crow defined what it meant to be black (a second-class citizen). Today mass incarceration defines the meaning of blackness in America: black people, especially black men, are criminals. That is what it means to be black.

The fact that more than half of the young black men in any large American city are currently under the control of the criminal justice system (or saddled with criminal records) is not - as many argue - just a symptom of poverty or poor choices, but rather evidence of a new racial caste system at work.

The mass incarceration of poor people of color, particularly black men, has emerged as a new caste system, one specifically designed to address the social, economic, and political challenges of our time.
