More than 56 percent of Americans think college debt poses a bigger threat to the U.S. than the North Korean leader, based on a survey of 1,000 Americans aged 18 and older, taken in September.

There is no question that student debt is on the rise. More than 44 million Americans have taken out loans to pay for college and their debt totals $1.4 trillion. For those in their 20s, the average debt is $22,135. For those in their 30s, it's $34,033.

"Kim Jong Un is a rogue dictator that will soon have the ability to attack the U.S. with a nuclear missile, which sounds a bit more pressing than student loan debt," said David Chen, the founder of Millennial Personal Finance.
