America is suffering from a student-loan debt crisis.

While wages have increased by 67% since 1970, according to a 2018 Student Loan Hero report, college tuition has increased at an even faster rate. Consequently, student debt has reached record levels.

It's part of the Great American Affordability Crisis. Coupled with the fallout from the recession and a high cost of living, student-loan debt has made it difficult for millennials to save and has forced them to delay milestones like getting married, buying a house, and having kids.

Democratic presidential candidates have been proposing policies to offset the cost of college. Sen. Elizabeth Warren introduced a $1.25 trillion plan to forgive most existing student-loan debt and provide universal free college. John Delaney, Rep. Seth Moulton, and Sen. Kirsten Gillibrand have proposed student-debt forgiveness or subsidized college for students who go into national service.

Meanwhile, Sens. Bernie Sanders and Amy Klobuchar, Rep. Eric Swalwell, and the entrepreneur Andrew Yang have offered proposals to reduce the cost of college and the burden of student loans.
