Botswana isn’t that low income: slightly above the world average by PPP apparently: https://​​en.wikipedia.org/​​wiki/​​Economy_of_BotswanaNot that I think this necessarily makes applying your idea there bad, just important not to fall into stereotypes about Africa, when Botswana is a famous success story. (Yes, it’s still poor, but far less than it was at independence.)
Oops—corrected, sorry!
