Seriously, guys, read some of the interviews with survivors. Read about the justice that didn't come (ever) for the owners of that company. Read about the total disregard for life and limb (of others, of course). You read that and you try to argue with me about unions. No, the teachers in Wisconsin aren't fighting for unlocked fire exits so they don't burn to death. Yes, they are fighting for quality of life, and in many ways symbolic and tangible, that fight started after the Triangle fire.
I had classes in that building when I was at NYU. In my AP American History class we had a whole unit on the rolling intersection of the Industrial Revolution, the Gilded Age, and the New Deal, so the location of the Triangle fire was already in my sphere of knowledge when I had my first classes as a freshman Drama major. These days, that's primarily a College of Arts & Sciences building, but most of my required theatre studies classes and a handful of electives were there. I had several, over my four years, on the eighth floor where the Triangle fire started. It's a neat old building. Technically NYU connects two buildings there; I forget what the other one's called, but it's the home of CAS and has beautiful views over the Village and Washington Square Park. Really beautiful, with lots of staircases, lots of fire hoses, lots of sturdy fire escapes, lots of sprinklers.
Something else I experienced frequently while at NYU? Student teacher strikes. I don't know what the situation is like now, but the president (John Sexton?) had a reputation for exploiting student teachers. Furthermore, the student teachers weren't allowed to unionize. A lot of the protests and pickets I witnessed took place at the northeast corner of Washington Square Park, right at the College of Arts & Sciences building, right where the Triangle Shirtwaist Company operated.
