The Internet and the World Wide Web are often seen as part of a new "electronic frontier," with profound implications for the future of communications, the society and the economy. The slogan "the Internet is free" echoes the "free land" mantra of the Turner thesis. Indeed, opposition to pay walls and subscription services resembles the pioneer quest for free land unencumbered by ownership claims. Scholars analyzing the Internet have often cited Frederick Jackson Turner's frontier model.    Of special concern is the question whether the electronic frontier will replicate the stages of development of the American land frontier. Wikipedia is a major presence on the electronic frontier, and the Wikipedia editors have been explicitly compared to the pioneers of Turner's American frontier in terms of their youth, aggressiveness, boldness, equalitarianism and rejection of limitations. 
The divorce revolution's collective consequences for children are striking. Taking into account both divorce and non-marital childbearing, sociologist Paul Amato estimates that if the United States enjoyed the same level of family stability today as it did in 1960, the nation would have 750,000 fewer children repeating grades, million fewer school suspensions, approximately 500,000 fewer acts of teenage delinquency, about 600,000 fewer kids receiving therapy, and approximately 70,000 fewer suicide attempts every year ( correction appended ) . As Amato concludes, turning back the family-stability clock just a few decades could significantly improve the lives of many children.
Needless to say, not every child exposed to lead is destined for a life of crime. Everyone over the age of 40 was probably exposed to too much lead during childhood, and most of us suffered nothing more than a few points of IQ loss. But there were plenty of kids already on the margin, and millions of those kids were pushed over the edge from being merely slow or disruptive to becoming part of a nationwide epidemic of violent crime. Once you understand that, it all becomes blindingly obvious. Of course massive lead exposure among children of the postwar era led to larger numbers of violent criminals in the ’60s and beyond. And of course when that lead was removed in the ’70s and ’80s, the children of that generation lost those artificially heightened violent tendencies.
