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.

I think it's critically important for people to understand that this system of mass incarceration governs not just those who find themselves in prison on any given day, but also all those who are in jail, on probation or parole, as well as all those who are just months away from being locked up again because they are unable to find work or housing due to their criminal record.

Once you have been branded a criminal or felon, you are typically trapped for life.

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.

In the 1990s - the period of the greatest escalation of the drug war - nearly 80 percent of the increase in drug arrests was for marijuana possession, a drug less harmful than alcohol or tobacco and at least, if not more, prevalent in middle class white neighborhoods and college campuses as it is in the 'hood.

It's important to teach students about the reality of the system, that it is in fact the case that they are being targeted unfairly, that the rules have been set up in a way that authorize unfair treatment of them, and how difficult it is to challenge these laws in the courts. We need to teach them how our politics have changed in recent years, how there has been, in fact, a backlash. But we need to couple that information with stories of how people in the past have challenged these kinds of injustices, and the role that youth have played historically in those struggles.

What are people released from prison expected to do? How are they expected to survive? Can't get a job, locked out of housing, and even food stamps may be off limits. Well, apparently what we expect them to do is to pay hundreds or thousands of dollars in fees, fines, court costs, and back child support (which continues to accrue while you are in prison).
