It’s not uncommon to find a Ugandan taxi driver in Rwanda’s capital, Kigali, just as one regularly meets Zimbabwean Uber drivers in South Africa. But there is a big difference.

East Africa has made greater strides towards the free flow of people crossing borders and seeking work than most of Africa. Only the Economic Community of West African States (ECOWAS) is in the same league.
