Abstract
In this essay, Alexander Sidorkin offers a conceptual critique of the human capital theory that makes erroneous assumptions about the nature of student work and the private cost of schooling. Specifically, human capital theorists underestimate the private cost of schooling by taking low‐level manual labor as the basis for estimating students’ forgone earnings. This does not take into consideration the nature of students’ labor of learning. In the essay, Sidorkin describes student work as a form of labor, not an investment activity, and considers the implications such an understanding of student work has for school reform.
