In its early years, the United States boasted one of the highest -perhaps the highest - literacy rates in the world. (Of course, slaves and women didn't count in those days.) As early as 1635, there had been public schools in Massachusetts, and by 1647 compulsory education in all townships there of more than fifty households'. By the next century and a half, educational democracy had spread all over the country. Political theorists came from other countries to witness this national wonder: vast numbers of ordinary working people who could read and write. The American devotion to education for all propelled discovery and invention, a vigorous democratic process, and an upward mobility that pumped the nation's economic vitality. Today, the United States is not the world leader in literacy. Many of those judged literate are unable to read and understand very simple material - much less a sixth-grade textbook, an instruction manual, a bus schedule, a mortgage statement, or a ballot initiative. And the sixth-grade textbooks of today are much less challenging than those of a few decades ago, while the literacy requirements at the workplace have become more demanding than ever before. The gears of poverty, ignorance, hopelessness and low self-esteem mesh to create a kind of perpetual failure machine that grinds down dreams from generation to generation. We all bear the cost of keeping it running. Illiteracy is its linchpin.
