For reasons that have stunningly little to do with crime or crime rates, we, as a nation, have chosen to lock up more than two million people behind bars. Millions more are on probation or parole, or branded felons for life and thus locked into a permanent second-class status.

Many people don't realize that financial incentives have been built into the drug war that guarantee that law enforcement will continue to arrest extraordinary numbers of people, particularly in poor communities of color, for minor drug offenses that get ignored on the other side of town.

Once you're labeled a felon, the old forms of discrimination - employment discrimination, housing discrimination, denial of the right to vote, denial of educational opportunity, denial of food stamps and other public benefits, and exclusion from jury service - are suddenly legal. As a criminal, you have scarcely more rights, and largely less respect, than a black man living in Alabama at the height of Jim Crow. We have not ended racial caste in America; we have merely redesigned it.

Today it is perfectly legal to discriminate against criminals in nearly all the ways that it was once legal to discriminate against African Americans. Once you're labeled a felon, the old forms of discrimination - employment discrimination, housing discrimination, denial of the right to vote, denial of educational opportunity, denial of food stamps and other public benefits, and exclusion from jury service - are suddenly legal.

I think it's important to encourage young people to tell their own stories and to speak openly about their own experiences with the criminal justice system and the experiences of their family. We need to ensure that the classroom environment is a supportive one so that the shame and stigma can be dispelled.

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.

If the drug war was waged in those communities it would spark such outrage that the war would end overnight. This literal war is waged in segregated, impoverished communities defined largely by race, and the targets are the most vulnerable, least powerful people in our society.
