Derived in the eighties through a series of (now archived) articles in The New York Times, the Pizza Principle — also known as the “New York City Pizza Connection” — maintains that since 1960, inflation and other factors have caused the the price of both a slice of pizza and a single ride on the subway to rise at a nearly identical rate.
