Great video Graham! I love economics and talking about everyone's concept of what money is. I thoroughly enjoyed it!
"Money" is also a learned concept. Think of the child who valued their bottle cap collection. They value other people's trash. They would rather have a new example for their collection, than cash.
My wife is depressed, literally, if the bills are 100% paid but there is no extra money left to shop for things that we don't even need. IT must be spent! Otherwise, why have it?
She feels like things are horrible because she can't go through the act of looking for things we might need? The admission price to enjoy the ritual of consumerism with her friends and share it later.
I am the optomist. I am happy that there is food, shelter, health, and that the bills are paid. I don't shop for New Things to need.
Hahah. I like that kind of optimism.
