Why Are So Many Americans in Prison?

Leon Neyfakh in Slate:

Criminal justice reform is a contentious political issue, but there’s one point on which pretty much everyone agrees: America’s prison population is way too high. It’s possible that a decline has already begun, with the number of state and federal inmates dropping for three years straight starting in 2010, from an all-time high of 1.62 million in 2009 to about 1.57 million in 2012. But change has been slow: Even if the downward trend continues, which is far from guaranteed, it could take almost 90 years for the country’s prison population to get down to where it was in 1980 unless the rate of decline speeds up significantly.

What can be done to make the population drop faster? Many reformers, operating under the assumption that mass incarceration is first and foremost the result of the war on drugs, have focused on making drug laws less punitive and getting rid of draconian sentencing laws that require judges to impose impossibly harsh punishments on people who have committed relatively minor crimes. But according to John Pfaff, a professor at Fordham Law School, neither of those efforts will make a significant dent in the problem, because they are based on a false understanding of why the prison boom happened in the first place.* Having analyzed statistics on who goes to prison, why, and for how long, Pfaff has emerged with a new and provocative account of how the problem of mass incarceration came to be. If he’s right, the implications for the prison reform movement are huge and suggest the work needed to achieve real progress will be much harder than most people realize.
