If you can find something fulfilling that is a good cultural fit, great. But lots of people get caught up in the "grass is always greener somewhere else" mentality and end up job swapping constantly to find some mythical culture that perfectly aligns with them. And maybe that works if your primary goal is what's in it for you. But it can also have the effect of minimizing your impact, which is counter-productive for a goal of contributing to something beyond yourself.

The point that may have gone missed in my original comment was the perspective was focused on "being effective" and not "working somewhere I like". One is somewhat selfish, the other is not.

FWIW, I'm not saying anyone should have to care about their impact. It's just ironic when I see people constantly job-hopping with the stated goal of finding a cultural fit so they can have said impact.
