If you want an example of how British rule helped 'save' a people, look at Somalia

This video breaks it down but the northern region (now called Somaliland) was once ruled by the British but they left the tribes to rule most of the area, only enforcing control over the port areas, compared to Italy that enforced top down control.

Decades later after a massive civil war, the British decision saved Somaliland as they still had the tribal structure so had elders with respect that called for peace and were listened to. Compared to the rest of Somalia that is mad max without the cool vehicles.
