"When "Nickel and Dimed" was published in May 2001, cracks were appearing in the dot-com bubble and the stock market had begun to falter, but the book still evidently came as a surprise, even a revelation, to many. Again and again, in that first year or two after publication, people came up to me and opened with the words, "I never thought..." or "I hadn't realized..."

At the time I wrote "Nickel and Dimed," I wasn't sure how many people it directly applied to -- only that the official definition of poverty was way off the mark, since it defined an individual earning $7 an hour, as I did on average, as well out of poverty. But three months after the book was published, the Economic Policy Institute in Washington, D.C., issued a report entitled "Hardships in America: The Real Story of Working Families," which found an astounding 29 percent of American families living in what could be more reasonably defined as poverty, meaning that they earned less than a barebones budget covering housing, child care, health care, food, transportation, and taxes -- though not, it should be noted, any entertainment, meals out, cable TV, Internet service, vacations, or holiday gifts. 29 percent is a minority, but not a reassuringly small one, and other studies in the early 2000s came up with similar figures.

Perhaps the constant suspicions of drug use and theft that I encountered in low-wage workplaces should have alerted me to the fact that, when you leave the relative safety of the middle class, you might as well have given up your citizenship and taken residence in a hostile nation.

Most cities, for example, have ordinances designed to drive the destitute off the streets by outlawing such necessary activities of daily life as sitting, loitering, sleeping, or lying down. Urban officials boast that there is nothing discriminatory about such laws: "If you're lying on a sidewalk, whether you're homeless or a millionaire, you're in violation of the ordinance," a St. Petersburg, Florida, city attorney stated in June 2009, echoing Anatole France's immortal observation that "the law, in its majestic equality, forbids the rich as well as the poor to sleep under bridges..."

That could be me before the blow-drying and eyeliner, and it's definitely Al Szekeley at any time of day. A grizzled 62-year-old, he inhabits a wheelchair and is often found on G Street in Washington, D.C. -- the city that is ultimately responsible for the bullet he took in the spine in Phu Bai, Vietnam, in 1972.

He had been enjoying the luxury of an indoor bed until December 2008, when the police swept through the shelter in the middle of the night looking for men with outstanding warrants. It turned out that Szekeley, who is an ordained minister and does not drink, do drugs, or cuss in front of ladies, did indeed have one -- for "criminal trespassing," as sleeping on the streets is sometimes defined by the law. So he was dragged out of the shelter and put in jail.
