There's a book by Robert Heinlein that goes into what it would take to send things back to earth. I think the book is "The Moon is a Harsh Mistress". In it, it is more about sending projectiles, but the concept is the same. That due to the gravity differential, it is much cheaper to send things back to earth from the moon than the other way around. But as some of the commentary on the page you linked suggests, it wouldn't be trivial to mine on the moon. I'm sure that someone will figure out the ROI eventually. But I'm stuck on the image of getting a dragline up to the moon.
