For those who say that the war on drugs and the system of mass incarceration really isn't about race, I say there is no way we would allow the majority of young white men to be swept into the criminal justice system for minor drug offenses, branded criminals and felons, and then stripped of their basis civil and human rights while young black men who are engaged in the same activity trot off to college. That would never be accepted as the norm.

Most Americans violate drug laws in their lifetime, but the enemy in this war has been racially defined. Not by accident, the drug war has been waged almost exclusively in poor communities of color, even though studies have consistently shown - for decades - the people of color are no more likely to use or sell illegal drugs than whites.

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.

For the rest of your life you must check the box on employment applications asking the dreaded question: "Have you ever been convicted of a felony?" And once you check that box, the odds are sky high that your application is going straight to the trash. Hundreds of professional licenses are off-limits to people convicted of felonies.

The war on drugs has been the engine of mass incarceration. Drug convictions alone constituted about two-thirds of the increase in the federal prison population and more than half of the increase in the state prison population between 1985 and 2000, the period of our prison system's most dramatic expansion.

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.
