Cities outlast every plan made for them. An urban planner exists to shape how\nland, buildings, movement, and people fit together over decades — deciding what\ngets built where, who benefits, who pays, and how the place will feel long after\ntoday's politicians are gone. The work exists because land use generates\nexternalities no single owner internalizes: a factory's smoke, a tower's shadow,\na highway's traffic. Someone must think about the whole, on a horizon longer than\nany election.
