Wow. I recently discovered Botswana during a deep dive on Wikipedia. Botswana is the size of Metropolitan France, which has a population of ~60 million, but Botswana only has a population of 2.2 million! Resources? They have the most productive diamond mine in the world that consistently produces the highest quality large diamonds in the world.
GDP per capita? 18,500+ USD. They are solidly middle class by global standards.
Also, as I understand, the country lies just outside of the tsetse fly belt, which is very important for human development. Interestingly (and sadly), they also have one of the highest rates of HIV infection in the world, but seem to be managing it very well. (Wiki says: <<As of 2014, Botswana has the third-highest prevalence rate for HIV/AIDS, with roughly 20% of the population infected.>>)
