It's not hatred. It's self-interest. The very heart of capitalism. A rational response to incentive structures.

You're the one sacrificing your own self-interest for pride and are upset that others refuse to do so.

edit: And I get it, I don't optimize my own career like this, focusing more on what I enjoy to work on at the moment. But I don't begrudge people who do optimize nor do I claim to be better than them. If anything they are acting in a much more rational and organized way to their goals than I am.
