I'm late to this article by 7 hours, way down at the part where nobody reads the comments anymore, but I do find it therputic to respond sometimes, so I will.
I have to first laugh at the neckbeard movie theater employees claiming people chained to desks want to defend their lifestyle, "defending the man" and whatever "modern day slave" type comments they want to pull from the beatnik bible. Very few people WANT to work a 60+ hours week. But you don't have much of a choice in the matter. The big problem is that if you won't do it, there's someone waiting to replace you who will, so you have to do it. Even if you're salaried, with no overtime - the best you can hope for is a little recognition and a bonus. If you don't work those exhausting hours, you will be replaced by someone who will. Employment is better than unemployment, so that's what you do, unless you want to work 22 hours a week and live in your parents basement.
My first job out of college I averaged 70+ hours a week - and I was on a salary BELOW $30,000. I had graduated 7 months ago and took a bad offer just to finally have "a" job. But it wasn't worth it. I got to a point where I worked through my weekends, ten hour days, and got to 34 days in a row when I finally told my boss I was clearly being abused. Within a few weeks, I was fired. The guy they hired to replace me started at $46,000. Valuable lesson learned: never undersell yourself just to get in. Raises don't happen as frequently as they did in our parents' generations, and frankly, you'll never even get one of those if you don't stick your neck out and ask.
I've job hopped a bit, and was even at a job where I would work about 50 hours a week, clients would call and email at all hours of the night and I had to be able to respond to those calls, too. My boss, one day, would tell me that these things weren't expected of me, and the next day ask me why a project wasn't moving as quickly as he wanted it to. To mitigate some of those problems, I asked him to prioritize the multiple tasks I had in front of me. He would decide what got finished in what order (usually forcing him to choose between pet projects and profits).
The simple fact is that it's still an employer's market out there. Unemployment is still just high enough that they have their pick of the litter and if you don't live up to their expectations, you're gone, and another warm body can fill your chair. The problem isn't so much that people are willing to do this, the problem is that employers are expecting them to do this. It is the expectation set by the "driven" few at the top, who expect all of their employees who earn a tiny percentage of what the guy up top earns, to be just as driven as they are. I'm not going to "make partner" as an IT guy, why should I have to work just as hard at your law firm, accounting firm, medical practice, etcetera?
