Basically South Asians were brought over a few centuries ago by the British to work in clerical and administrative roles because blacks weren't capable. When the British left South Asians, through industry and intelligence, started dominated the economy. Lazy blacks started crying racism and their God King Idi Amin gave South Asians 72 hours to leave the country. Uganda's economy collapsed because South Asians made up the bulk of the businessmen, doctors, and large-scale farmers and since they had all been kicked out there was no one left to work.
