… simply put, in urban centers there are plenty of people who will partake in the same types of consumption (economies of scale) to uphold amenities like baseball stadiums, opera houses, and theaters and will drive down fixed costs for expenditures such as massages, organic food, and happy hour. Simultaneously, there are enough people that the “long tail” of consumption (economies of scope)— ethnic restaurants, high-end boutiques , and avant-garde theater— will also be in demand. This interplay of significant demand for the same things and the large sum of idiosyncrasies that emerge from having so many people with diverse backgrounds and preferences in the same place is what propels so many choices in urban centers. The sheer number of diverse inhabitants both drives the endless options of city amenities to be produced and creates the lines around the corner for every noodle/ cupcake/ cronut shop in town. In short, demand meets supply irrespective of the product or service.
