"Human trafficking is an international problem but it also happens in Michigan," writes Carrie Booth Walling, Albion College assistant professor of political science, in a January 31, 2015 op-ed column in the Flint Journal. "It happens in urban centers, suburban communities and rural areas. Trafficking is a form of modern-day slavery in which people profit from the control and exploitation of others whether or not victims cross international or state borders." Labor trafficking, in particular, is a major problem in Michigan, she adds.
