I don't know that "should" is the right word. It's possible and reasonably common in software to obtain career fulfillment beyond simply making a lot of money; I don't think you have some moral obligation to do that, but you should understand that other people do and that this is why they may have work style preferences which seem strange or confusing to you.

I'm more than mercenary for my family, friends, co-religionists, and above all – god. But yeah, I don't care a bit about my boss, and "co-workers".

Football players are mercenaries but they still work synchronously with teamlmates.
