From Texas Standard:
College has become a prerequisite for most high-paying jobs in the U.S., but college itself is out of reach for millions, and that number is growing. And the Federal Reserve Bank of New York says that in the past 10 years, student loan debt has grown by more than 100 percent. People ages 19 to 29 hold more than $1 trillion in student debt, and that's just the Millennial generation. With a wide-open Democratic primary field, it's almost certain that college affordability will be an issue during the 2020 presidential campaign.
Adam Harris writes in The Atlantic that the current crop of Democratic presidential candidates have focused their attention on how to make college affordable in the future, proposing free college tuition or policies that would allow students to leave school without debt.
Harris says that prior to the 2016 election, momentum had been building nationally for some sort of free college program. But once Donald Trump was elected president, that momentum shifted to the states.
