Why on earth would we want to pay off the loans of someone who took those years off from work and took out loans instead? I didn't go without sleep for 3 years so I could turn around and pay off school loan debt for someone who made an easier choice! If I'd wanted to do that, I would have skipped the job for those years and taken out my own loans.
Okay, adding another factor... what if you fell in love with someone who had huge loans because he'd gone through a very expensive program, like medical school? And had worked as much as he could, but hadn't been able to avoid getting loans? Would you still feel that he had taken the easy way out?
