I was very grateful that Apple had a policy against unpaid internships and I got one of their three library internships when I was getting out of library school. I hadn't thought about the social inequality aspect.

I worked my way though undergrad originally and happily managed to get jobs related to my field even if they didn't pay much. Of course that was back before internships where fashionable. I don't think I heard the term (outside of medicine) until going back to grad school in the late 80s.

Thanks for sharing the article.
