A couple different things jump out at me, and they're both along the lines of Darwinian thrift:
1) The world generally doesn't go to those with the best values or the best expansions of empathy, it goes to those who can match sperm and eggs best, and since there are specific parameters to that (such as status for example) a lot of people just optimize for what's critical for getting their seed into the next generation - ie. not a lot of room for being 'human' without losing that race.
2) When the set and setting is so filled with not only zero-sum but negative-sum games, and many forms of success require algorithm over human, it turns into the sort of cut-throat competition where if someone else is doing poorly or oppress - great! Better them than me! Woohoo!... and yeah, that lasts about until the time they get oppressed, and the victors react in the same way.
it's not that humanity as a whole should or is like this, it's more like certain people came up with the idea that we could expand and improve values while completely forgetting that human vs. human competition, and really - to state it broadly - nature, works in this sort of manner. It means that most people trying to make paradise on earth - whether through political philosophy, self-help, secular humanism, even new age - get eaten by these traps because so many of the belief systems they take on in trying to make the world a better place completely forget or ignore that these dynamics exist.
Someone recently dropped a particularly interesting quote by a guy named Donald Kingsbury:
Tradition is a set of solutions for which we have forgotten the problems. Throw away the solution and you get the problem back. Sometimes the problem has mutated or disappeared. Often it is still there as strong as it ever was.
While there was a lot that was wrong that we had to fix, such as racism and sexism, we also demolished many instantiations of Chesterton's Fence, and we did so.... I really think high on fossil fuels... really thinking that what we have now comes from a superiority that we have to our ancestors, and really the only superiority we have is that we found ways to burn millions of years of stored sunlight to have this massive energy surplus that made what we have today possible.
At the end of the day I think there are certain mistakes that most people will make in every generation. Today's beliefs being the unshakable laws of reality is one of them. Another is the idea that if you give people the facts on an issue that they'll be able to come to sensible conclusions (which completely ignores motivated reasoning, conformity considerations, and furthermore whether or not the idea helps them beat other people in the fertility game).
