I don't want to exaggerate; having as many African American men as we've had in the criminal-justice system, and the amount of time it takes for the damage done by that to wash through our society and our communities, the disadvantages born out of kids being undiagnosed with mental-health problems early, or not getting the kind of exposure to reading and math when they're 4 or 5 or 6 years old, that carries a cost.
