The Depth Crisis
Lazonick's institutional diagnosis of the moment when sustained immersion in a domain loses its economic rationale—not because depth has become less valuable but because the governance structure that made depth economically rational has been dismantled.
For most of the twentieth century, the large American corporation solved a problem that markets alone could not: it made depth economically rational. A young engineer joining a major industrial firm in 1955 could afford to spend a decade mastering a complex technical domain because the retain-and-reinvest corporation guaranteed something the market did not—a career. The investment in depth was bilateral: the worker invested years of concentrated study in firm-specific and field-specific knowledge, and the firm invested in training, mentorship, stable compensation, and the organizational infrastructure that allowed deep expertise to compound over time. William Lazonick's research traces the systematic dismantling of this arrangement—through the shift from
retain-and-reinvest to
downsize-and-distribute governance—and identifies the depth crisis as the moment when AI completes what four decades of financialized corporate governance had been making true by degrees: the economic marginalization of the kind of deep, patient, practice-dependent expertise that the postwar corporation once considered its most valuable asset.
