In 2006, the first of 77 million baby boomers reached age 60. In two years they will be eligible for early retirement benefits from Social Security. In five years they will be eligible for Medicare. As they retire, the boomers will stop paying taxes to fund America's elderly entitlement programs and begin collecting benefits instead. Over the next three decades, the number of retirees will double. However, due to declining fertility rates, the number of workers contributing to the system will fall from three for each retiree receiving benefits to two for each retiree. This will place a severe strain on working Americans to pay promised benefits to the elderly.
