I suspect you've never spent any meaningful amount of time in the local environments, or you wouldn't have made this comment.

As I elaborated on in another comment, it is commonplace to find that people who have little to no education and resources are missing countless opportunities to implement simple improvements to almost everything.

This mindset of "locals know best" is, frankly, toxic. (just think about the locals wherever you live to see how incompetent they are as well)

What is needed is genuine collaboration and communication between people living in whatever situation and others who are fortunate to have more access to information, resources, education on critical thinking etc...
