I think I was most impressed with their college plans (start at community college, don't get anything from mom & dad, graduate without debt), especially since they have 3 or 4 kids already living that dream, even going onto graduate school in some cases (except for the one kid who will wind up with a $90k loan!).
Think it's also great that the kids said themselves that they aren't any worse for wear. If you raise kids to respect money, they won't want for everything.
I wonder if they read MMM...
