Not those who were settled in Africa. They were the colonial middleclass and were landed right in it on independence. My suggestion is that between the wars the colonial powers seek to maximise their assets and ship in settlers from India, China and South East Asia on the scale of late 19th century settlers to the US to provide cheep but reasonably skilled and moderately educated manpower. They as otl prosper causing huge resentment and on independence all hell breaks loose.
