ROSS DOUTHAT: The Parent Trap.

Some of these cases have been reported, but some are first-person accounts, and in some the conduct of neighbors and the police and social workers may be more defensible than the anecdote suggests.

But the pattern — a “criminalization of parenthood,” in the words of The Washington Post’s Radley Balko — still looks slightly nightmarish, and there are forces at work here that we should recognize, name and resist.

First is the upper-class, competition-driven vision of childhood as a rigorously supervised period in which unattended play is abnormal, risky, weird. This perspective hasn’t just led to “the erosion of child culture,” to borrow a quote from Hanna Rosin’s depressing Atlantic essay on “The Overprotected Kid”; it has encouraged bystanders and public servants to regard a deviation from constant supervision as a sign of parental neglect.

Second is the disproportionate anxiety over child safety, fed by media coverage of every abduction, every murdered child, every tragic “hot car” death. Such horrors are real, of course, but the danger is wildly overstated: Crime rates are down, abductions and car deaths are both rare, and most of the parents leaving children (especially non-infants) in cars briefly or letting them roam a little are behaving perfectly responsibly.

Third is an erosion of community and social trust, which has made ordinary neighborliness seem somehow unnatural or archaic, and given us instead what Gracy Olmstead’s article in The American Conservative dubs the “bad Samaritan” phenomenon — the passer-by who passes the buck to law enforcement as expeditiously as possible. (Technology accentuates this problem: Why speak to a parent when you can just snap a smartphone picture for the cops?)

And then finally there’s a policy element — the way these trends interact not only with the rise of single parenthood, but also with a welfare system whose work requirements can put a single mother behind a fast-food counter while her kid is out of school.

And, more significantly, a social-welfare bureaucracy that needs these cases to make work for itself. Coupled with a sad abandonment of traditional remedies for overreaching officialdom.

And I wrote something similar on the subject a while back.
