I agree with you there about some interns being very busy. I do remember interns that had a lot of self imposed pressure to perform. If they even had say a minor issue with their work issued laptop they would be in a panic because of the time lost.

Also totally agree with you not having to work so many hours, but this is exactly why they love the college grad pipeline. So many fresh workers with something to prove.

The problem with nothing stopping you from leaving campus for lunch is that it's hard to convince your work-buddies to join you. Free is very compelling to some. And all your co-workers plan their meetings around this truncated lunch break.
