He talks about that too. You’re psychologically more likely to spend MORE money when using a card vs cash.
When cash leaves your hand, it creates a negative response in your brain (triggers pain sensors). When you use your card, your brain doesn’t get that negative response, and you think you’re getting the goods for free, so you spend more money than you would if it were cash.
The rewards are a way of getting you to keep using the cards. Just think about it. Do you think you’re getting a leg up on the credit card company? Would they just give away so much stuff if they weren’t coming out on top?
¨I want to quit my credit cards, but the rewards are just so good!¨ That sounds like someone who can’t quit a toxic relationship.
