The document discusses three approaches to managing socio-economic diversity in healthcare:
1) Market-based approach (USA): Individuals bear full responsibility for costs. Issues include high insurance premiums and denial of coverage.
2) Shared responsibility approach (Singapore): Government intervenes and shares costs through subsidies. Both government and individuals share responsibility.
3) Government-financed approach (Sweden): Government provides substantial subsidies and services, with healthcare sometimes being free. Challenges include high taxation rates needed to fund the system.
The document uses case studies of the US, Singapore, and Sweden healthcare systems to illustrate the three approaches and their advantages and disadvantages in managing socio-economic diversity.
