Here's an indication of how burdensome student loans have become: About one-third of millennials say they would have been better off working, instead of going to college and paying tuition.

That's a according to a new Wells Fargo WFC +0.57% study which surveyed 1,414 millennials between the ages of 22 and 32. More than half of them financed their education through student loans, and many say the if they had $10,000 the "first thing" they'd do is pay down their student loan or credit card debt.

That's no surprise when you consider student borrowing topped the $100 billion threshold for the first time in 2010, and total outstanding loans exceeded $1 trillion for the first time in 2011. Student loan debt now exceeds credit card debt in the U.S. which stands at about $798 billion.

Delinquencies are also on the rise. The number of borrowers who are at least 90 days late on student loan payments has jumped from 8.5% in 2011 to 11.7% today, according to a study by the New York Federal Reserve.

The problem sometimes is that not all college educations are worth their cost since they can't guarantee a high-paying job to help pay off that student debt. A report from the National Association of Consumer Bankruptcy Attorneys says the rising student debt problem can have a bad impact on the economy. Even in the best of economic times when jobs are plentiful, young people with considerable debt burdens end up delaying life-cycle events such as buying a car, purchasing a home, getting married and having children.
