Why do productivity gains worsen inequality instead of benefiting everyone?
Core argument: Wage convergence across high-productivity and essential-service sectors drives up health care and education costs faster than overall inflation, leading to disproportionate spending burdens on low-income households that spend 2–3x more of their income on these services vs. high-income households.
The real threat from Baumol's cost disease lies in the uneven distribution of productivity gains, not the inevitable shift toward less-productive industries. As firms in highly productive sectors demand highly credentialed workers, wages for similar roles, such as doctors, increase, exacerbating inequality as low-income workers face higher costs for essential services like health care. Although productivity growth could potentially benefit everyone, governments often fail to adequately tax the winners and compensate the losers. Misunderstanding the Baumol effect, politicians sometimes cap spending on education and health, worsening the issue.
