Abstract: This paper discusses five examples of the conventional wisdom that has often been expressed in the social security debate, even among academic economists. These are: 1. The major problem in most social security systems is that of demography: people simply live too long. 2. Disregarding the issue of demography, a Pay-As-You-Go system is inferior to a fully funded system since the former usually has a lower rate of return. 3. Disregarding the portfolio aspect (which might favor a PAYG system), a funded system dominates a PAYG system in a world of certainty. 4. The social security system is a suitable instrument for intergenerational risk sharing. 5. The government is a safe and reliable provider of insurance.
