Correction, slight but important: psychologists don't tell us what is "normal", they tell us what is "healthy" and "unhealthy", in the realm of human mental functions.
Let's take one simple example: addiction. Psychology defines addiction as a malfunction in which you keep on doing a certain behavior even when you know it's harmful for you. There's no moral judgement here, it is considered a "malfunction" because obviously, a well balanced mind, interested in self preservation like all alive creatures are, wouldn't do such a thing. So addiction goes in the "unhealthy" column.
Now, if you take it to the society (=many humans) level: I don't know how much addiction is there in your society; mine is bursting at the seams with it... So addiction, unhealthy as it is, is also "normal" (meaning "common", "mainstream").
Conclusion: we live in a psychologically unhealthy society, whose "bricks" are unhealthy individuals, who give value to things that should not be valued, and despise things that should be essential.
