Wow! Wotta list! Of 54 African nations you ‘found’ one; a 50 year old nation which is three quarters desert, land locked and ravaged by chronic drought. Hm........
As for SA, its 1 out of 13 and Chile’s success is questionable at best; given it’s chronic political instability.
Well Chile is in the process of undoing all of the good things Pinochet did.
