Price of parking

Initially, the developer pays for the required parking, but soon the tenants do, and then their customers, and so on, until the price of parking has diffused everywhere in the economy. When we shop in a store, eat in a restaurant, or see a movie, we pay for parking indirectly, because its cost is included in the price of merchandise, meals, and theater tickets. We unknowingly support our cars with almost every commercial transaction we make, because a small share of the money changing hands pays for parking.
