I agree if you're working in some drone farm. Without a personal stake, why do people feel enthusiastic about following orders that keep them locked up at work all day? I understand that there may be coercion, like the threat of being fired, but if you're just writing software for your company, where does the enthusiasm for long hours come in? I'm freelance, and I love working on my projects. I often work long hours. I hardly stop. But I have a 100% stake in what I do and generally choose projects I believe in, like endangered language preservation or stuff that I find intellectually stimulating. Why would someone want to work at Microsoft or Google past 6pm? Why do people give their souls to hives?
