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.

For those interested in learning more about corporations and private individuals profiting from the caging of human beings, I highly recommend the book "Prison Profiteers: Who Makes Money From Mass Incarceration."

Private prison companies are now listed on the New York Stock exchange and are doing quite well in a time of economic recession (and depression in some communities). But that's just the tip of the iceberg.

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.

What defenders of the system typically fail to acknowledge is that the reason violent offenders comprise a fairly large percentage of the state prison population is because they typically receive longer sentences than non-violent offenders.

The United States does have the highest rate of incarceration in the world dwarfing the rates of even highly repressive regimes like Russia, China or Iran. This reflects a radical shift in criminal justice policy, a stunning development that virtually no one - not even the best criminologists - predicted forty years ago.

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.
