Makes no sense to me why a society which has adopted a materialistic/atheistic view of the world (even implicitly), would be so obsessed with the idea of human 'happiness', or the idea of 'not being depressed'.
Why would a universe that was a mere accident and spurted out of nothing, produce beings whose goal should be happiness? Why not feeling neutral or even unhappy?
What, the workings of evolution are somehow compelled to create beings that are happy? For what purpose? Wolves or say, bears, evolved, procreated and hunted just fine without feeling anything in particular at all.
