Courts Weigh Legality of Unpaid Internships — Page 2

I was recently at a show and struck up conversation with the young man sitting next to me. He was telling me about how he moved from the West coast because he got a 60-hour-a-week position with a company that is well-known in the New York theatre community. He then told me that he was living in a hostel in the heights using money from student loans because he was completely uncompensated, only receiving a Metrocard to get to and from work every day. I just don't understand how there are not regulations that prevent things like this.

What exactly is the difference between interning and volunteering?
