In case that was not meant as sarcasm:

Are the people in the current US administration, or the tech leadership, or the people in power in Israel or Russia looking particular nice to you or interested in the wellbeing of all humans?

Were the European colonialists nice to the people in Africa or South America or the settlers in North America to the natives?

People are super nice - to their own ingroup. The relationship to everyone else is less friendly, especially if power differences are involved.
