Fighting over scraps isn't the best way to see it, IMO. If I'm busting my ass at a job, it's because I share the vision (if not the capital) of the people I'm working for, want to see that vision executed, and want to take an active part in executing it well.

If that is not the case, it doesn't matter how much I'm being paid, I'm not going to be happy ("self-actualized") for long. Likewise, whether I work 40 or 60 hours a week has no bearing on this. I imagine quite a few people joined Twitter because they believed in the company's stated mission and the vision of its founder. The mission and vision have now changed, so it's appropriate for some of those people to move on, voluntarily or otherwise. Framing it as some kind of Marxist class struggle sheds no light on the issue, and isn't helpful in the least.
