This isn’t totally true. Poorer people frequently live and work on land that is substantially more economically productive. If you have 20 working adults using the same amount of space as a single family, you’ll usually have a lot more tax revenue from the same amount of land. Without requiring much more infrastructure. Which means in terms of tax revenue versus outlays, poorer districts frequently subsidize wealthier ones.
