This study documents that the notion of Social Security as a minimal safety net is consistent with the views of both Adam Smith and Friedrich Hayek and that private social security accounts are inefficient and subject to moral hazard and huge productivity losses. It also introduces a novel approach to long-term investing suitable for perpetual funds consistent with the empirical phenomena of risk premia and mean reversion, including no asset sales and the use of short-term borrowing on a rollover basis to cover negative net inflows
