Dos India have the exportable middle class for that? I can understand the logic since it would be a cheap move comparatively versus Europe or Americas but without a glut of mobile professionals and a hospitable environment, it seems like Africa would chew them up.
You raise a good question.
I base my thoughts on Indian populations here and Saudi Arabia. We have an explosion of multigenerational Indian families that pretty much have taken over the running of hotels/motels. There are professionals and doctors forming the basis of Indian communities in some rather small American cities. The same is true of doctors and engineers and accountants and such in the Gulf region.
In my thought some will migrate from where they are to Africa where they will be in control rather than in the background. They will expand in to large colonies in East Africa drawing others from their home in India.
They will grow and get control over time.
