3x rule is not a rule but a guideline. It applies more to the average person.
If you give someone 100 dollars a day they have to buy food, clothes, rent, education, transportation. You give them 1000 dollars a day they still have to buy the same things. They can then use this leftover to buy nicer food or nicer house. This is why values of homes can get so high in areas. For the people getting 1000 they chose where ti spend this extra money. For people with 100 a day they don’t have extras to reallocate towards rent.
