My experience is that there are a lot of synergies to be leveraged. It's almost ridiculously easy to start a successful startup in a place like Nigeria or Ghana which either:

- Providing things Nigeria excels at to Western markets (e.g. the same types of call center models India started out with a few decades back).

- Launch services in Nigeria common in Western markets but not yet there.

- Integrate Western and African models

Those sorts of things tend to benefit everyone involved on both sides of the pond. Compared to, for example, making web frameworks, there is a lot more low-hanging fruit. Silicon Valley has an almost unlimited supply of people wanting to do startups for people like themselves. This leaves many other markets under-tapped.

In terms of fostering local entrepreneurs, that happens naturally. Look at China, Taiwan, Korea, or Japan. They started with this model, at which point locals noticed they could do the same better and cheaper themselves, while retaining more profit. India is about half-way there now. It's very hard to foster entrepreneurship by telling. It's very easy by modeling.

China, Korea, Taiwan, India, and Japan never turned into Western colonies, as you're predicting.
