Spending a few months interning as a student is one thing, but I see in a lot of industries that are employer's markets, such as film, magazines, etc, internships are really just a way for employers to avoid having to pay someone to do grunt work. They know people are so desperate for work that they are willing to work for free and exploit it. It's the same situation with people who feel obligated to do lots of unpaid overtime because they're "lucky to even have a job". That's why labour laws were invented.
