Kenya is by and large the most artificial of states in SSA.It's coonery in which they operate with. They rest their pride on christianity and being anglophone but those same english christians looked down on them and even positioned Indians above them , hence why large parts of the economy is operated by them.
They did this in all colonies so it's not really specific to Kenya. But the mental subservience they come with is the same in anglo/franco christian african countries coupled with Islamophobia and rabid hate for arabs as an extension of it.
At least Muslims Arabs and Somalis elevated them into equal status and collaborated with them on the coast where we lived in product lives side by side with the Swahilis.
The Great Lakes states have actual history of pre-colonial statehood and Tanzania has linguistic homogeneity that Kenya doesn't.
