Update: I posted about it on the Huffington Post. I will be contributing to them occasionally from now on, and will post links back and forth.
Also, a number of the people who've responded have wished that I dwelled more on the unfair class implications of internships--the fact that you have to be able to pay to get your foot in the door. A story by Jennifer 8. Lee in the NY Times 2 years ago underlined this point, which I think is a very good one.
A reader writes:
I had several friends who were forced to make a choice over whether to gain valuable experience and connections as an unpaid intern or earn money that summer and live at home. Many of them were forced to choose the later thus leaving them out of the summer internship club with nothing to put on their resume and losing out to those with enough money. I call it a club because that’s exactly what it is – if your family has enough money then you’re in. If you’ve walked around Capital Hill in summer time you’ll know exactly what I’m talking about.
