Final answer:
The US insurance regulatory system is unique due to the state-level regulation and the conflict between low insurance prices and universal coverage.
Step-by-step explanation:
The two criteria that make the US insurance regulatory system unique in the world are:
- Primarily regulated at the state level: The US insurance industry is mainly regulated by individual states rather than at the federal level. This means that each state has its own set of rules and regulations for insurance companies to follow.
- Conflict between low insurance prices and universal coverage: The state insurance regulators in the US attempt to achieve two goals - keeping insurance prices low and ensuring that everyone has insurance. However, these goals can often conflict with each other and become entangled in politics.
