Herein lies the problem: assuming that all people in a location/area are like that. Black and white thinking is the antithesis to a humanistic approach. Even worse is thinking your perspective is the "best" one and that whatever decisions you make are, of course, best for everyone.

We'd do a lot better if we accepted that everybody is different and homogeneity and the drive to force it on others is a disease of the mind. Yeah, there are plenty of assholes, but consider why: because someone taught that person as they were growing up (either directly or indirectly) that being an asshole protects you. I'm frequently an asshole because I got picked on when I was younger. But guess what? For the right situations, it works. For others a more gentle touch is fitting. That's the dynamic to encode into tech: leveraging a combination of deterministic and non-deterministic systems to create adaptable systems that relish in a mess as opposed to fall apart because they're too rigidly shaped to accommodate the most and only favor the perspective of the few. That's how you get inhumane systems: they're designed and maintained by people living completely different lives from the people they're building for.
