A new study suggests upward mobility is more difficult in Illinois than many would think. Although educational attainment and career choices have the biggest influence over a person's income potential, the economic class into which they are born also plays a role. Students from lower-income households tend to earn less than their wealthier peers, even after earning similar degrees and going into similar fields. Sarah Cashdollar, associate director of the Illinois Workforce and Education Research Collaborative, talks with CNI's Peter Hancock about the report, "Precarious Prospects."
