This same article was posted on Democratic Underground.
A number (although not all) of the posters said they would have kept the money.
So far, not a single freeper has said he or she would keep the money.
It’s dangerous to feel superior, but I am glad that the vast majority of freepers try to live according to traditional values.
I’m pretty sure I would return it. Of course, that’s easy to say when it just theoretical, and not an actual heaping pile of cash on ~my~ kitchen table. But I really think I would give it back. I’ve never been tempted with that much, but I’ve returned lesser amounts of found money... plus if I kept it, I’m sure it would nag at me forever.
