The question is rooted in that Indians under british colonialism could go to any british colony and do business and even cases of them moving to non british colonies and doing business (Look at the Tata) family. This in turn created situations where you had old money Indian families even through Colonialism. Seems like from an African perspective even the so called elite caught the sharp end of the sword.
The Indians and Chinese and other Asians would be the only groups that I can think of that would have been able to have done that. The Arabs may have also done so. The only Africans that I would think that could have done it were the Berbers, Hausa and Mande people because of their histories as long distance traders.
