About 2-3 hours after you posted, a different section of this discussion was started bendbro and Rury; My personal belief is that SOME cases of your Z are caused by a 'learned helplessness' situational conditioning filter. The world isn't always fair and sometimes even earnest effort that in an ideal world should yield some sort of positive result has none. Hypothetically the human social creature evolved in small tribes / large families. Possibly in those cases slight negative reactions like that would be corrected by the presence of the family. In the distraction model of recovery possibly by redirection to a more useful effort that would yield positive outcomes for the individual and group. In modern cities, it is very easy to end up alone, or nearly alone, with very few to rely on. Even if someone has friends in a city they might be real effort to reach, and that is assuming they've got time. If there's that effort involved maybe you don't even hang out with them and drift apart until even chance meetings cost effort and thought.
