The college degree used to be the ticket to a good middle class job. That is officially over, according to a new study by the Center for College Affordability and Productivity.
It found that nearly 1 out of 2 Americans with college degrees are working at jobs they're overqualified for. While less than 5 percent of retail sales clerks had college degrees in 1970, the study found that 25 percent did in 2010. And 15 percent of taxi drivers were college grads in 2010, versus just 1 percent in 1970.
