I mean there is some merit to it. Some people get a raise or promotion and immediately buy a new car or rent a new apartment or use up all that extra money somewhere else.
I recently bought a house. The previous owner had a tenant living in it whom was trying to save enough to buy the house. That renter owned and drove a Cadillac escalade. I drive a hatchback beater car. If i had her car and gas payments, i doubt I'd have saved enough for a down payment.
