In the 1970s, deindustrialization and urban decay forced national, state, and local policymakers to focus more intensely on public-private partnerships as mechanisms of economic regeneration. This approach to postindustrial regeneration intersected with a rising generation of liberal politicians: labeled variously “Atari Democrats,” “neoliberals,” or “New Democrats,” they sought to orient the Democratic Party towards market-friendly politics. This intersection was evinced in the regeneration of Lowell, Massachusetts, a city dealing with decades-long industrial decline. Contrary to narratives that emphasize public-private partnerships only as instruments of privatization, however, Lowell’s experience exemplified how successful regeneration required an expanded role for the state: this article reinserts the “public” into “public-private partnership.” Excavating this reality in Lowell’s heretofore understudied history also demonstrates that New Liberals’ market-friendly political posture obscured deeper policy continuity with twentieth-century liberalism. Far from emerging locked into an ideological embrace of “neoliberalism,” the New Liberals sought to reimagine liberalism’s commitment to developmentalism.
