I think about that a lot too, but I come at it from the other angle. A lot of people drowning in student loan debt spending 5-10K a year on vacations seems like a bad move, especially in the context of the debt forgiveness.
I've never been big on vacations. They are a luxury. I never really got to go on many as a kid: dad worked long hours in the summer and we didn't have much money. As a result, I've never really been big on them as an adult.
