This work investigates the causal relationship between industrial rationalization and the persistent problem of unemployment in the early 20th-century economy. John Atkinson Hobson, a prominent British economist and social critic, utilizes his expertise in underconsumption theory to analyze how increased industrial efficiency and capital concentration contribute to structural labor displacement. He argues that the drive for rationalized production often outpaces consumer demand, leading to systemic economic imbalances that manifest as chronic joblessness.

Economists and historians recognize this text as a significant contribution to the development of heterodox economic thought regarding labor markets. Readers frequently note the dense, analytical prose characteristic of Hobson's critique of classical economic models.
