Actually, my own personal observations would tend to agree with you... I see dysfunction everywhere I look, and my social & family circles are brimming with people who've suffered from family dysfunction. If I took my own observations as a fair random sample, I would definitely believe your conclusion.
I come from a dysfunctional family background. I've spent a lot of time in therapy & recovery, and learned a considerable amount about this kind of behavior.
I'm also aware that my own experience biases me toward seeing this behavior, everywhere. If anything, I tend to over-pathologize people around me, as an artifact of practicing the kind of thinking that I needed to do in order to get better... And my personal sample of observing the human race is pretty heavily weighted toward other people who definitely have pathologies, because I've spent so much time with them in meetings and groups.
It's really common for people with this kind of history to feel like "Everybody I meet turns out to be messed up... All my friends, family, and romantic partners seem to be dysfunctional, too." This isn't an accident, though... Messed up people are drawn to other messed-up people, for a lot of reasons.
Anyway, point being... I have to work to maintain awareness that my personal observations are probably not a fair, random sample of the population. I don't trust my intuition in this regard, because I know that I've been so hyper-focused on it, my whole life.
