The Lesson: Money might not be the root of all evil, but it certainly can’t buy happiness
As Shown By: The Weasley family have hardly two galleons to rub together, and yet they are presented as the happiest and most loving of all Rowling’s characters. The Malfoys on the other hand are rolling in it, and yet they spend much of the saga wracked with guilt, worry and anxiety. And the less said about those grasping goblins the better. It doesn’t exactly turn out well for them, does it?
