Times have certainly changed. I remember watching Duck Tales growing up and loved watching Scrooge McDuck swimming around in his silo of gold coins and precious stones:
However, kids these days have no clue what a gold coin is, or what it's worth. It's all about "the Benjamins" and Mr. Krab's paper fetish:
He even gets excited about worthless "copper" pennies. I think every cartoon that displays money uses the green variety. This is unfortunate. May we all teach our kids sound economics and the proper form of money!
