Books: Leisureville: Adventures in America's Retirement Utopias

The ageism practiced by the approximately 1,500 "gated geritopias" is actually the only form of housing discrimination sanctioned by Congress. Under the logic that special services are needed to support an aging population, they may exclude families with children under 18.

Responding to the charge that these seniors are dropping out of society, a Villager known as Mr. Midnight puts it this way: "I paid my dues. Now it's your generation's turn. You work it out. I'll be here kissing the ladies." (And kiss they do. Blechman finds teeming singles bars and horny seniors who want to "use it before I lose it!" In 2006, the Villages' alarming std rate made national news; one doctor claimed she saw more cases of herpes there than in Miami.)

With 78 million boomers hitting retirement age and seniors-only communities recruiting 55-year-olds, Blechman raises the prospect of a significant portion of the population retiring into never-never land. Some communities have gone so far as to cut their financial ties with local school districts and vote against paying some of their local taxes. Blechman doesn't have much respect for elders who try to escape the social contract in their golden years. "That's not citizenship," he writes. "That's secession."
