Tess Vigeland: And finally, to this week’s Marketplace Money piggy award. Our little blue plastic friend is heading to Tempe, Ariz., always makes me laugh, and listener Samantha Allen. She wrote to us this week with a response to the question raised on our last show: “When does a parent’s money stop being the parent’s money?” Simple, she said. “Money for college is not like a loan that needs to be paid back through good behavior. It’s more like an investment. You’ll be paid back when we take care of you, our parents in your old age, from the money we made, in the job we’re only able to get because of our degrees.” You may not agree, but her financial argument is simple, to the point, and for that, we bestow upon her a pig.
