On the other hands, I often donate to wikipedia, supporting local FOSS communities and mentoring young students. Currently helping my friend with his air pollution measurement station project too. All that I won't be able to do if I take a lower paying job but more meaningful job (previously I was working as a civil engineer, building bridge and stuff).
May be you can find a different work which may pay a bit less but doesn’t create negative value for the society?
All other "meaningfulness" is just pure bonus. And no: I am not unhappy, nor unfulfilled.
Providing my family, doesn't have "any cost". It costs at least 50K€/year around here and, if my LinkedIn feed and the official stats concerning my domain of expertise are to be believed, I could slam the door any day and start at another tech company within a week.
But, assuming we are in a TV show, yes. I would gladly harm tens of thousands of unnamed, faceless nobodies and please tens of thousands of others if it helped me keep my loved ones out of the gutter. Especially if it meant playing with the cool tech at Palantir :-)
On a planetary scale? Universal Scale? Of course it doesn't matter, but what would be the point of caring about that except at length? We're not universal scale. I'm not a planet. I'm a human, and I care about other humans and the communities I'm part of.
