[In Brief] Core cities benefit from the expansion of the tax base that supports their feature services and attractions. [Rationale] It is frequently argued that suburban communities take advantage of their core cities by offering close access to the major attractions of the core city (especially events and facilities) without having to pay for the direct or indirect costs of those attractions. Consolidated communities spread those costs over the entire metropolitan area, preventing some communities from "free riding" on others. [Factor]
