In the war on drugs, state and state law enforcement agencies have been rewarded in cash by the federal government - through programs like the Edward Byrne Memorial Grant program - for the sheer numbers of people arrested for drug offenses.

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.

In many large urban areas, the majority of working age African American men now have criminal records and are thus subject to legalized discrimination for the rest of their lives. It is viewed as "normal" in ghetto communities to go to prison or jail.

Middle-class white children, children of privilege, are afforded the opportunity to make a lot of mistakes and still go on to college, still dream big dreams. But for kids who are born in the ghetto in the era of mass incarceration, the system is designed in such a way that it traps them, often for life.

I was inspired by what students have done in some schools organizing walkouts protesting the lack of funding and that sort of thing. There are opportunities for students to engage in those types of protests - taking to the streets - but there is also writing poetry, writing music, beginning to express themselves, holding forums, educating each other, the whole range.

We have not ended racial caste in America, we have merely redesigned it.

Plenty of drug dealing does happen in the 'hood, but it happens everywhere else in America as well. In fact, some studies suggest that where significant differences in the data can be found, white youth are more likely to engage in illegal drug dealing than black youth.
