Not the guy you replied to but man....you're just writting your own fanfiction here.

>white colonists build themselves cities using indigenous labour
White colonists built modern cities in a place where only primitive huts villages existed.
This was done using European knowledge and technology as well as local low skilled labour.
These cities were in most places not "for white people" as settler colonialism wasn't really a thing outside of Rhodesia and South Africa.
Some white workers did live temporarily in these place to run the administrations and organize local development, but they were never the majority of the population of these cities.
>have to house them somewhere, slums develop
Slums developed at the periphery of the major cities built by Europeans because these developed cities attracted a massive amount of local Africans from the surrounding areas, who wanted to enjoy the modern infrastrucres and technology brought by European colonizes, as well as the better paid jobs that were avaiable in these developing cities.
Some were housed in proper housing in the modern parts of the city, but the influx was so massive that those that couldn't find proper housing started building "slums" (usually just the usual precolonial style villages of huts) in the outskirts
>whites attempt to control decolonisation, failure means war
>failing that they loot, burn what they can't carry and run
This whole part is pure fantasy.
The vast majority of Subsharan Africa obtained independence without war, and even in the few places that saw a war of independence, the cities and infrastructures brought by European colonization were mostly intact when Europeans left.
