Here’s the bigger problem this helps to solve: Money is a source of mystery to children. They sense its power, so they ask questions, lots of them, over many years. Why isn’t our house as big as my cousin’s? Why can’t I have a carnivorous plant terrarium? Why should I respect my teachers if they earn only $60,000 per year? (Real question!) Are we poor? Why didn’t you give money to the man who asked you for some? If my sister can have Hello-Kitty-themed Beats by Dre headphones, why won’t you get me the Bluetooth-enabled Lego Mindstorms set? (It’s only $349, and it’s educational, Mom!)
