Tressie McMillan Cottom, an assistant professor of sociology at Virginia Commonwealth University, joins us to discuss her book, Lower Ed: The Troubling Rise of For-Profit Colleges in the New Economy. Cottom examines the rapid growth of for-profit colleges -- over two million students are currently enrolled in for-profit colleges like ITT Technical Institute and DeVry. She reveals how they contribute to growing inequality and looks at the marketing strategies that these schools use to recruit students, despite the well-documented predatory practices of some and the campus closings of others.
