Yeah, but your 'tough titty' is also simply demotivating.
Why is it that the most obscene thing to entertain is some compromise?
Because the 'good of the whole' simply doesn't outweigh a single person's baby to them - ever. People simply stop sharing at all. You can pretty much count historical exceptions to this selfishness on your hands.
We are selfish creatures. How do we make ourselves less selfish? That's the hurdle.
