If nobody cared, art would not exists. Nobody would do science. Civilisations would not be built. Health care would not exists. And nobody enjoys living in a shit hole. People collectively do make decisions which are selfless, so long they know there is a positive outcome. People stop caring about something soon as they recognise their efforts is wasted or it's all for nothing.
I tend to agree. Anytime I encounter negativity or cynicism of this level, it reminds me of a speech by David Foster Wallace: https://www.youtube.com/watch?v=ms2BvRbjOYo
