... as birth rates fell drastically, and the life expectancy at age 60 expanded enormously, fewer workers are now being forced to support more and more retirees. The result is a huge rise in social security taxes in every nation with a pay as you go system. The combined tax on employees and employers in the United States, excluding contributions to medicare, is now 12.4 per cent and rising, and that percentage is much higher in Japan and most Western European nations.

Pay as you go systems are in trouble throughout the world in good part because of changes in the number of workers per retiree, but also because of politically determined decisions that changed the system from saving for old age to an inefficient and complicated welfare system for some of the elderly. For example, despite the growing mental and physical health of older persons, political pressures in all nations with pay as you go systems forced a restructuring of social security payouts to encourage retirements at earlier ages than even the originally established age 65. In the United States many retirements occur age 62 or earlier, while Italians retire frequently while in their mid fifties, and very early retirement is not uncommon also in Germany, Belgium, and many other European countries.
