Why should more Americans have access to community college?

Earlier this year, the President laid out a proposal to make community college free for responsible students for two years.

In our growing global economy, Americans need to have more knowledge and more skills to compete -- by 2020, an estimated 35 percent of job openings will require at least a bachelor's degree, and 30 percent will require some college or an associate's degree. Students should be able to get the knowledge and the skills they need without taking on decades' worth of student debt.
