Was Trump on to something with apprenticeships?

President-elect Trump was well known before he became a reality TV star. But what elevated him to the higher reaches of the “famous” category was “The Apprentice,” in which he launched a fleeting national craze of tersely stating, “You’re fired.”

Apprenticing made for engaging television. But is it a good idea in the truly real world? Is it something Trump should encourage as president? A new paper argues that what sounds like a fine idea could be very hard, perhaps even dangerous, to foster.
