HIGHER EDUCATION BUBBLE UPDATE: The Devastating, Lifelong Consequences of Student Debt: It’s threatening fundamentally American ways of life.

We see this with other lifetime measures, such as how entrepreneurial people are. A recent study by Brent W. Ambrose of Pennsylvania State University, and Larry Cordell and Shuwei Ma of the Federal Reserve Bank of Philadelphia, found “a significant and economically meaningful negative correlation between changes in student loan debt and net business formation for the smallest group of small businesses.” This makes sense. You can keep your high student loan burdens low if you stay with an established employer. But if you strike out on your own, you’ll have less and more volatile income when you start. This is harder to manage with student loans, which also impacts your credit rating. Again, we can see the short-term student loan burdens staying the same, even though lifetime choices are much more limited as a result.

The lifetime framework also puts front and center something the Brookings study largely hand-waves: the rapid increase in how long people are paying off their student debt. Though the percentage of income that student-loan debtors pay stays the same, the length they are paying those loans is up 80 percent. What was once an average length of 7.4 years in repayment in 1992 is now 13.4 years. All things equal, a large increase in the length you will be paying student loans means you will dedicate a larger portion of your lifetime income to student loans. This burden goes missing by narrowly looking at a month-to-month basis.

This has major consequences for people’s ability to build wealth. Indeed, much of the current energy in analyzing student loan burdens are looking at this longer dynamic, and how it interplays with the ability for people to amass savings. As Richard Fry of Pew found, using the same data set as Brookings, “households headed by a young, college-educated adult without any student debt obligations have about seven times the typical net worth ($64,700) of households headed by a young, college-educated adult with student debt ($8,700).” Fry also finds that those who took out loans are less satisfied with their financial situation compared to people without loans. Similar results have been investigated and found by the Federal Reserve Bank of St. Louis.

This, in turn, has major consequences for how young people will ultimately transition into adulthood. According to Dora Gicheva of the University of North Carolina at Greensboro, student debt decreases the long-term probability of marriage by a significant amount.

Do tell.
