Could technology have improved the lives of the Luo Tribe in the book Yes We Can?   

The Luo tribe is Nilotic tribe descended from pastoral nomads who migrated south from Southern Sudan to the land around Lake Victoria near the end of the 15th Century. They migrated in at least five waves starting approximately 1500 AD. The Luo gradually displaced the Bantu-speaking tribes living in the region that were the ancestors of the modern Luhya and Kisii (Gusii) tribes. By the 1840's the Luo had formed a tight knit society with ruodhi or regional chiefs or kin
 also, The Luo tribe does not practice male circumcision. Instead the removal of the six lower front teeth is done in an initiation. This practice has fallen out of favor.
