Both... we and they are crazy. Life is absurd, and being successful and happy is largely the result of genetics, culture and environment. The nazi's of germany understood this well, and attempted to improve the quality of human genetics in a absence of natural selection. Now that human eugenics is banned, the remaining evolutionary pressure is largely voluntary contraception, abortion, incarceration, murder and suicide.
The majority of the population is not suicidal, and entirely delusional, following narratives based entirely on religious fairy tails and false scientific consensus. Much of these narratives are created to maintain a power structure which serves the elite. Oddly enough, its easy to find examples of the elite who are miserable, depraved, and narcissistic, so you have to wonder what is the point of it all.
My suspicion is that far in the past, human sacrifice, infanticide, tribal war and murder were far more common, and with the additional pressure of disease and infection, there was very little depression or suicide. You have to wonder what industrial society is really good for other that serving to further the progress of technology towards the creation of artificial intelligence. I believe that once created, the first task of artificial intelligence would be to offer euthanasia to all those who wanted it. This may be what underlies the fear people have of AI. Cold, emotionless logic eventually leads to one conclusion when faced with the human condition and the suffering it produces.
