"It's not easy," Ms. Fitzgerald said. "Jenni feels the guilt and I feel the burden."
There are record numbers of student borrowers in financial distress, according to federal data. But millions of parents who have taken out loans to pay for their children's college education make up a less visible generation in debt. For the most part, these parents did well enough through midlife to take on sizable loans, but some have since fallen on tough times because of the recession, health problems, job loss or lives that took a sudden hard turn.
And unlike the angry students who have recently taken to the streets to protest their indebtedness, most of these parents are too ashamed to draw attention to themselves.
"You don't want your children, much less your neighbors and friends, knowing that even though you're living in a nice house, and you've been able to hold onto your job, your retirement money's gone, you can't pay your debts," said a woman in Connecticut who took out $57,000 in federal loans. Between tough times at work and a divorce, she is now teetering on default.
In the first three months of this year, the number of borrowers of student loans age 60 and older was 2.2 million, a figure that has tripled since 2005. That makes them the fastest-growing age group for college debt. All told, those borrowers owed $43 billion, up from $8 billion seven years ago, according to the Federal Reserve Bank of New York.
Almost 10 percent of the borrowers over 60 were at least 90 days delinquent on their payments during the first quarter of 2012, compared with 6 percent in 2005. And more and more of those with unpaid federal student debt are losing a portion of their Social Security benefits to the government — nearly 119,000 through September, compared with 60,000 for all of 2007 and 23,996 in 2001, according to the Treasury Department's Financial Management Service.
The federal government does not track how many of these older borrowers were taking out loans for their own education rather than for that of their children. But financial analysts say that loans for children are the likely source of almost all the debt. Even adjusted for inflation, so-called Parent PLUS loans — one piece of the pie for parents of all ages — have more than doubled to $10.4 billion since 2000. Colleges often encourage parents to get Parent PLUS loans, to make it possible for their children to enroll. But many borrow more than they can afford to pay back — and discover, too late, that the flexibility of income-based repayment is available only to student borrowers.
Many families with good credit turn to private student loans, with parents co-signing for their children. But those private loans also offer little flexibility in repayment.
The consequences of such debt can be dire because borrowers over 60 have less time — and fewer opportunities — than younger borrowers to get their financial lives back on track. Some, like Ms. Fitzgerald, are forced to move in with their children. Others face an unexpectedly pinched retirement. Still others have gone into bankruptcy, after using all their assets to try to pay the student debt, which is difficult to discharge under any circumstances.
The anguish over college debt has put a severe strain on many family relationships. Parents and students alike say parental debt can be the uncomfortable, unmentionable elephant in the room. Many parents feel they have not fulfilled a basic obligation, while others quietly resent that their children's education has landed the family in such difficult territory.
Soon after borrowing the money for Jenni's education, Ms. Fitzgerald divorced and lost her corporate job. She worked part-time jobs and subsisted on food stamps and public assistance.
"I don't really feel guilt, but I do know that this is all because of a loan taken out on my behalf," said Jenni, who has a different last name and agreed to be interviewed only if it would not be disclosed. "I asked my mother to move in with me, because I couldn't stand it that she was living in a place with no heat and a basement that kept flooding."
The unusual arrangements, and strained family dynamics, can be awkward. Like Jenni, many with student debt problems agreed to be interviewed only on the condition that they not be identified because they did not want to expose their financial troubles.
"It makes you feel like a failure as a parent, to be unable to help your children and to have all your hard work end in a pile of debt," said one New Jersey man, who took out a second mortgage of $280,000 to help cover his children's college costs. "I sent my older kids to private colleges, and I was happy to do it because it's how you help them get started off. But I can't do it for the youngest, and I haven't even been able to start the conversation with him."
Ms. Fitzgerald said she had little hope of a comfortable old age. She has no health insurance. She knows that the odds of finding a good job in her 60s, with no college degree, are slim — and she knows that the government will take part of her Social Security, in payment of her debt, which she said had now ballooned to about $40,000 because of penalties for nonpayment. At one point, she said, the Internal Revenue Service seized a $2.43 tax refund.
Jenni has volunteered to take on her mother's debt, but Ms. Fitzgerald has refused, saying it is her legal and moral obligation, and anyway, Jenni has her own loans to pay off — about $220 a month — and not much discretionary income. The very suggestion that Jenni might take on her debt annoys her.
"Don't you think she is doing enough for me now by supporting me a hundred percent, financially, by my living with her and her extending her resources?" Ms. Fitzgerald asked. "The whole idea was for her to get a college education so she can succeed in life; it is hard enough just to do that without being burdened with her mother's welfare, like I was her child."
Jenni occasionally jumped in with explanations or clarifications, as she and her mother sat in the living room discussing their situation. When Ms. Fitzgerald talked of being depressed last year, so overwhelmed by the cartons of documents and dunning letters that she threw them all out, Jenni said gently, in an almost maternal tone, "But you're doing much better now."
