I then consider three political principles and four economic principles that could guide the design and reform of social insurance programs. These ideas are then applied to unemployment insurance, Social Security pensions, health insurance and Medicare. A common theme is the advantage of incorporating investment based personal accounts in each of these programs. ER -
