There's an interesting review over at NRO of Ross Perlin's Intern Nation, a book that examines the growing and almost wholly invisible number of unpaid intern positions that are eagerly staffed by college students or recent college graduates. Many of them are in higher education or are referrals by academic work/study programs. All of them are uncompensated, a sizable number are illegal, and in many instances the interns actually pay to play.
The reviewer, herself a graduate student at Harvard, surveys the landscape of this strange workforce and ponders the social implications of its continued growth. The author, she reports, seems to think there's a revoultion brewing.
