Drawing on Chapters 11 and 12 of Barkan (2023), analyze one major policy challenge facing the contemporary U.S. healthcare system—such as high costs, insurance gaps, inequities, administrative complexity, or workforce shortages. How do the comparative health systems discussed in Chapter 11 help explain the sociological roots of this issue? What evidence-based policy strategies do recent peer-reviewed sociological studies recommend for addressing it? Support your response using the textbook and at least one recent peer-reviewed sociology journal article (≤ 5 years old)
