In my experience with consultants, McKinsey and their ilk do similar things in many other countries, too, and not just the poor African ones. It is not uncommon for government officials to retire to lucrative positions at these consultancies, in return for earlier favors. South Africa is different because their very liberal post-apartheid constitution gives journalists and whistleblowers a large amount of protection. They also have a good culture of investigative journalism, thanks to the anti-apartheid movement.
