While your ideas of morals in politics is great, politicians (and most people) don't care. Evolution has forced us to be better than anyone else at all cost.
I wouldn't go that far. We do cheer for humanity all the time. I was glued to the TV cheering for those miners. I stand at the finish lines of triathlons and see people finish these races who are also battling cancer. Humans are amazing and strong and good in a lot of ways. I try to cheer for humanity a lot more than I hate on it.
