An aged Native American chieftain was visiting New York City for the first time in 1906. He was curious about the city and the city was curious about him. A magazine reporter asked the chief what most surprised him in his travels around town. “Little children working,” the visitor replied.

Child labor might have shocked that outsider, but it was all too commonplace then across urban, industrial America (and on farms where it had been customary for centuries). In more recent times, however, it’s become a far rarer sight. Law and custom, most of us assume, drove it to near extinction. And our reaction to seeing it reappear might resemble that chief’s — shock, disbelief.

But we better get used to it, since child labor is making a comeback with a vengeance. A striking number of lawmakers are undertaking concerted efforts to weaken or repeal statutes that have long prevented (or at least seriously inhibited) the possibility of exploiting children.
