In general, the best government interventions target failures precisely – using cap and trade to put a price on air pollution, for example, or relying on the individual mandate to curtail adverse selection in health insurance – while letting market forces do the rest more efficiently than bureaucrats can.
总而言之，最佳的政府介入手段应当精确定位失灵之处——使用设限+交易去给空气污染定价或者强制参保去减少医疗保险中的逆向选择——并让市场力量比官僚更高效地去解决余下的其他问题。
