I recently commissioned a poll that asked adults of all ages about student loans. We asked how much student debt is okay, and how much is too much. One in five senior citizens and almost a quarter of adults between the ages of 35 to 49 agree that $20,000 to $50,000 in student loan debt is too much to borrow. Maybe that's because they are in the age range of folks in a position to hire young people. Maybe it's because college didn't used to cost so much. At any rate, people of college age, between 18 and 24, disagreed with the old folks; only 16 percent said graduating with that much debt is too much.
