Only Lang'ata has a working class majority. The rest is basically slums. Explains how a chokora like Sonko could escape from prison and win. Once people get that a fellow thug or slummer is in fact not the best answer to your predicament they will improve. Tribalism is bad enough - poorism is way worse. The accomplished guy is more likely to help - that why you run away to America or Europe and not to Somalia or South Sudan.
You see Pundit - class is a step backwards towards barbarism not an improvement over tribe.
