Today it is perfectly legal to discriminate against criminals in nearly all the ways that it was once legal to discriminate against African Americans. Once you're labeled a felon, the old forms of discrimination - employment discrimination, housing discrimination, denial of the right to vote, denial of educational opportunity, denial of food stamps and other public benefits, and exclusion from jury service - are suddenly legal.

The dramatically different manner in which we, as a nation, responded to the crisis presented by drunk driving and the crisis caused by the emergence of crack cocaine speaks volumes about who we value, and who we view as disposable.

The wave of punitiveness that washed over the United States with the rise of the drug war and the get tough movement really flooded our schools. Schools, caught up in this maelstrom, began viewing children as criminals or suspects, rather than as young people with an enormous amount of potential struggling in their own ways and their own difficult context to make it and hopefully thrive. We began viewing the youth in schools as potential violators rather than as children needing our guidance.

The mythology around colorblindness leads people to imagine that if poor kids of color are failing or getting locked up in large numbers, it must be something wrong with them. It leads young kids of color to look around and say: "There must be something wrong with me, there must be something wrong with us. Is there something inherent, something different about me, about us as a people, that leads us to fail so often, that leads us to live in these miserable conditions, that leads us to go in and out of prison?"

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.

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.

I say we haven't ended racial caste in America; we have merely redesigned it.
