It can't be entirely that. The tourists, at least, are leaving NY with the same stuff they brought with them. I think the real reason has to be that so many more people are in a good mood when they are leaving NYC than when they are going to NYC.The fight usually starts when someone tries to put something in a partially-full overhead bin and someone else says "Don't touch my stuff, asshole!" It goes downhill from there.
