The people that lend you money basically give you an answer based on the risk that they are willing to take. But just because a bank is willing to take a particular risk doesn't mean that that is the right amount for me to spend.
If you have loans, the first thing you want to do is say, "Okay, look I have a credit card, if I really need to borrow, I have this emergency money that I can get, but for now there is no reason for me to keep cash at zero percent interest rate and at the same time, pay all of this money out. So, I think people need to figure out quickly how to pay loans and how much cash they should really keep.
Imagine you have six loans, small to huge. People want to close loans and because of that, they try to pay off the small loans, but that's not the right strategy. The right strategy, of course, is to pay the loan with the highest interest rate. People make this mistake and it costs them lots and lots of money, it's a very expensive mistake because interest rates accumulate and become very, very expensive very quickly.
What people do is they pay the small loans first. Why? Because they enjoy making the number of loans smaller. But of course it is a very ineffective way to pay debt down.
Imagine you owe on five credit cards, you owe five debts. So which debt should you pay first? And the answer is very simple: You should pay the one with the highest interest rate first. But that's not what people do.
The problem is that people basically dangle debt in front of us. And the cost for the poor of course is much higher than for the wealthy.
Money are very difficult to think about. So, we think about money as the opportunity cost of money. So, we at some point went to a Toyota dealership and we asked people, what will you not be able to do in the future if you bought this Toyota?
If you think of people as making decisions actively, every time we think about the cup of coffee, we say, "How much will I enjoy the cup of coffee, what else could I not do in the future because I buy this cup of coffee?
Who would you trust right now? Which bank would you trust? Which investment would you trust? Do you really want to put your money; do you want to suffer more of these losses that we just had? You know, these volatility that we see is just unexplainable by any rational standards. Nobody has any clue about how to explain this, and nobody wants to experience that. So, we hold more money back, we don't necessarily want to invest in the market and by default, people are saving more.
Because cheating is easier when we can justify our behavior, people often cheat in small amounts: We can come up with an excuse for stealing Post-It notes, but it is much more difficult to come up with an excuse for taking $10,000 from petty cash.
The people who need to overcome temptation to the highest degree have the hardest time doing it.
In a world where everyone is behaving honestly, any dishonesty constitutes a big infraction. But, in a world where many people are behaving dishonestly, and the news is filled with stories of their infractions, even big infractions can feel small to the perpetrator.
Money is very difficult to think about. So, we think about money as the opportunity cost of money. So, we at some point went to a Toyota dealership and we asked people, what will you not be able to do in the future if you bought this Toyota? Now, you would expect people to have an answer. But people were kind of shocked by the question. They never thought about it before. So, the most we got was people said, "Well, if I can't buy this Toyota, if I buy this Toyota, I can't buy a Honda." What is this thing? What is this value of price? Very hard to think about it.
What kind of people would be able to rationalize better than other people? Better storytellers, right? Creative people, right? Because if you're creative, you find more ways to cheat and still yourself a story about why this is okay.
