Drunk driving contains a far greater risk of violent death than the use or sale of illegal drugs, the societal response to drunk drivers has generally emphasized keeping the person functional and in society, while attempting to respond to the dangerous behavior through treatment and counseling.

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.

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.

A massive new penal system has emerged in the past few decades - a penal system unprecedented in world history. It is a system driven almost entirely by race and class.

A new race-neutral language was developed for appealing to old racist sentiments, a language accompanied by a political movement that succeeded in putting the vast majority of backs back in their place. Proponents of racial hierarchy found they could install a new racial caste system without violating the law or the new limits of acceptable political discourse, by demanding 'law and order' rather than 'segregation forever'.

The nature of the criminal justice system has changed. It is no longer primarily concerned with the prevention and punishment of crime, but rather with the management and control of the dispossessed.

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