Social Security benefits typically replace around 35% of the typical worker's preretirement earnings, and the purpose of this Article is to show how pensions could and should be designed to replace, say, 40% of the typical worker's preretirement earnings throughout her retirement years. In particular, because so many public and private pension plans are underfunded, this Article focuses on how to fully fund those pensions."
