The problem is that nobody in tech can even really work for eight hours a day for long periods. People who work long hours almost always pad out the actual work with non-work. And the people who live at work are typically screwing around so much that they barely get any work done.

Yes, it makes sense to do all of this as a person working there, but I think it is telling that the companies let this happen. People can only work so much. Why not get the work out of them that you can, and then send them on their way?
