    For instance, Culum Brown, an Australian biologist who spent a period as a postdoctoral researcher in my laboratory at Cambridge, discovered that showing young salmon “video nasties” of other salmon being eaten by a pike was sufficient to train them to avoid large predators, a crucial life skill for a young fish. He was also able to “teach” salmon fry to consume appropriate novel foods by watching more experienced fish.113 Subsequently, some Queensland hatcheries exploited our social learning protocols as part of their efforts to enhance the returns of salmon and other fish introduced...

    Further research will no doubt refine these numbers, but the estimates are serious and thoughtful. Moreover, the estimates are surprisingly convergent on the key point: Writing off such a large fraction of our youth is an awfully expensive course of inaction.

    In addition to philanthropy and good works, religious involvement among youth themselves is associated with a wide range of positive outcomes, both academic and nonacademic.45 Compared to their unchurched peers, youth who are involved in a religious organization take tougher courses, get higher grades and test scores, and are less likely to drop out of high school. Controlling for many other characteristics of the child, her family, and her schooling, a child whose parents attend church regularly is 40 to 50 percent more likely to go on to college than a matched child of nonattenders.

    We Americans like to think of ourselves as “rugged individualists”—in the image of the lone cowboy riding toward the setting sun, opening the frontier. But at least as accurate a symbol of our national story is the wagon train, with its mutual aid among a community of pioneers. Throughout our history, a pendulum has slowly swung between the poles of individualism and community, both in our public philosophy and in our daily lives.7 In the past half century we have witnessed, for better or worse, a giant swing toward the individualist (or libertarian) pole in our culture, society, and politics....

    “The achievement gap between children from high- and low-income families is roughly 30–40 percent larger among children born in 2001 than among those born twenty-five years earlier.”17 That gap corresponds, roughly speaking, to the high-income kids getting several more years of schooling than their low-income counterparts. Moreover, this class gap has been growing within each racial group, while the gaps between racial groups have been narrowing (the
