WHAT CITY JOURNAL WROUGHT: In honor of his magazine’s 25 anniversary, Myron Magnet, City Journal’s founder and editor-at-large looks back at the worst of New York’s Bad Old Days, and how the city gradually turned itself around, at least for a time:

In 1983, the Mobil Oil Corporation, to show Mayor Edward Koch why it was contemplating leaving New York, videotaped the sordidness around its 42nd Street headquarters, near Grand Central. The camera caught the rotting trash, the pee-filled potholes, the degradation of the homeless hordes—some crazy and some shiftless—through which Mobil employees had to pick their way into the then-shabby, billboard-plastered station to catch trains home to their orderly suburbs, fragrant with new-mown grass. After shots of corporate headquarters located in similarly bucolic suburbs, the wordless video closed with the written question: “What do we tell our employees?”

Mobil’s answer, in 1987, was to move to Fairfax, Virginia. More than 100 of some 140 Fortune 500 companies headquartered in Gotham in the 1950s asked the same question and reached the same conclusion, pulling out their tax dollars and leading their well-paid workers into greener pastures in those pre–Rudolph Giuliani decades. They were among the million New Yorkers, many of them the elderly rich and the well-educated young, who fled Gotham in the 1970s and 1980s.

The squalor was only one problem. Another was crime. Of course, much of the disorder—the open dope-dealing, the public drinking, the streetwalkers serving every almost-unthinkable taste, the three-card-monte cardsharpers and their pickpocket confederates preying on the crowds they drew, the window-rattling boombox radios—was itself against the law. But these minor crimes deepened as a coastal shelf into burglary, car theft, armed robbery, assault, rape, and murder—one killing every four hours every day of the annus horribilis 1990.

Read the whole thing. Though curiously missing from a CTL-F search of Magnet’s article is the word “Blasio.” Perhaps someone might want to convert Mobil’s 1983 videotape to DVD or upload it to YouTube, as everything old is new again in the Big Apple. (Don’t mind the maggots.)
