I understand what you are saying, but I think you are missing an important concept. If you created more value than you spend, you have an extra. Other people want to spend more than they created. So what happens is that people who have the extra, can loan their value to those who have a deficit. This loaning can also be considered a service. People are not forced into renting. What Mr. Money Mustache is saying is "Hey, don't be the guy with the deficit, be the guy with the surplus, because everyone with the deficit will work for those with the surplus". What I hear from US with all their credit cards, it seems it's a culture of spending way more than you earn. Spending money that you will receive at the end of the month. Which is pretty stupid.
