But Botswana did not fail. It succeeded not just moderately well, but spectacularly. In the thirty years after independence it grew its per capita GDP faster on average (nearly 8 per cent) than any other country in the entire world – faster than Japan, China, South Korea and America during that period. It multiplied its per capita income thirteen times so that its average citizens are now richer than Thais, Bulgarians or Peruvians.
