The biggest threat to our economy? Student loan debt

If one were to ask me what I think is the most dangerous threat to our economy, the answer is very simple: student loans.

As I write this, we have more than $1.2 trillion of student loan debt. About 10 million federal students loans are taken out annually, and then there are the insanely dangerous private student loans on top of that staggering number.

And while 6.7 million borrowers in repayment mode are delinquent, the sad fact is that many lenders aren't exactly incentivized to work with borrowers. Unlike all other forms of debt, student loans can't be discharged in bankruptcy. Moreover, lenders can garnish wages and even Social Security benefits to get repaid. A new report by the Consumer Finance Protection Bureau details just how bad the situation is for private loan borrowers. (From Oct. 1, 2013, through Sept. 30, the agency handled about 5,300 private student loan complaints, an increase of nearly 38 percent from the previous year.)

And private student loans aren't the only problem. Do you know that from 2007 to 2012, the government made $66 billion in profit on federal student loans? We can all debate how our government should generate revenue to support federal spending programs, but doing it on the backs of young adults who need an education to compete in the increasingly competitive global workforce is just appalling.

Even if you don't have student loans, or know someone who does, you better believe this huge debt load is impacting your financial well being. When students of the greatest nation on Earth are buried with student loans, their ability to buy a home, to have disposable income, to be a vital participant of the economy, is greatly reduced.

A new snapshot of consumer debt released by TransUnion shows just what is going on. Total student loan debt has grown more than 150 percent since 2005. Inflation to blame? No. Overall prices rose just 22 percent or so between 2005-2014. The culprit here is more loans being taken out, and more borrowers getting hit with fees and penalties.

According to TransUnion, in 2005 student loans accounted for less than 13 percent of the total debt load for adults age 20-29. Today, student loans account for nearly 37 percent of that group's outstanding debt. Student loan debt's slice of the total debt pie for the age group nearly tripled! The average loan balance for that age group is now more than $25,500, up from $15,900 in 2005. Again, that is way more than inflation.

So what slice got smaller? Mortgages. From 63 percent of total debt for 20-29-year-olds in 2005 to less than 43 percent.

The Consumer Financial Protection Bureau's newest report on the private student loan industry noted that the Treasury Department recently acknowledged that the student loan market could "significantly depress demand for mortgage credit and dampen consumption."

Could? The TransUnion data show the impact is clearly being felt already. You better believe that the debt load carried by millennials has a serious impact on your finances. Nearly 70 percent of our economy comes from consumer spending, yet there's a significant demographic that has a very limited ability to consume. Weak demand mutes economic growth, which we can all agree is not ideal.

While the private student loan industry is the baddest of the bad actors (just read the CFPB report), even the much fairer federal loan program is not without its serious warts. The sizable profit margin is in part fueled by too high interest rates. The interest rate on federal undergraduate loans this year is 4.66 percent. For graduate students, the rate is 6.2 percent. For parents borrowing through the PLUS program, it's 7.2 percent. That's just for this year; rates are now tied to the 10-year Treasury note rate, which will likely mean higher student loan rates in the coming years simply because we're still hovering near historic lows.

The 4.66 percent for an undergraduate Stafford loan is at a time when qualified borrowers can get a 30-year fixed rate mortgages for around 4.3 percent for much of the year. If banks can make plenty of money lending out at less than the rate on a federal student loan—for 30 years—it is troubling that student and their families are charged more for shorter-term debt.

And don't tell me that extra rate cushion is to pay for the risk of student loans that are essentially handed out without any qualifying standards. (PLUS borrowers just have to be current on debt payments and not filed for bankruptcy recently.) Homeowners can default on a mortgage and have it discharged in bankruptcy. As I mentioned earlier, student loan debt is not dischargeable in bankruptcy. That's a pretty low risk.

Sen. Elizabeth Warren, D-Mass., has introduced legislation that would allow student loan borrowers to refinance their loans at rates below 4 percent for undergrads and under 7 percent for PLUS loans; essentially rolling back rates to where they were before this academic year, when Congress instituted its new higher-rate regime and eliminated a lower subsidized rate on Stafford loans entirely. That's not a break for student loan borrowers. It's fair and equitable, and could help ease an economic headwind that impacts all of us. Yet the bill has to date met strong Republican resistance.
