Daniel D'Amico begins his look at American mass incarceration by placing it in international context: Yes, we all know that we are a nation of jailers. But what have other countries been doing differently? Or the same? He notes that in recent years many other countries have dramatically increased their incarceration rates and incarcerated populations as well. He examines several proposed causes for our high incarceration rate, including racism, our free-market economic system, and our War on Drugs. He finds the latter the most persuasive of the frequently mentioned culprits.
