The essence of wealth is also a record. If you earned your money legally and ethically, without cheating, your net worth is the sum of the value you created for society. When you spend money, you're essentially clearing this record. Therefore, people with a lot of money are essentially owed goods or services by society as a whole. Why is Musk so wealthy? Because his value creation for human society is immense; he can't possibly spend all of it himself.
