Val MacQueen writes
Those expelled from East Africa were third generation immigrants to Africa, and had created assets and wealth. Which is why Idi Amin was so interested in them. Now, those families are again third generation immigrants, this time to Britain, and again they are rolling in wealth. How was this extraordinary feat accomplished twice?
The World Bank's book
Where is the Wealth of Nations? does not list Uganda, but it gives the
per capita wealth of Kenya as $6609. The CIA world factbook gives
per capita GDP of Uganda as $1700, compared with $1200 in Kenya. If wealth and GDP are proportional, that means that
per capita wealth in Uganda is less than $10,000. If you multiply that by the 40,000 South Asians made refugees by Idi Amin, they would now be worth $400 million collectively if they had remained in Uganda and had the average economic status of Ugandans (although presumably they would have been well above average). MacQueen's story lists several individual former refugees who are worth more than $400 million.
Mississippi Masala (1991) Directed by Mira Nair, (who later directed Monsoon Wedding and Vanity Fair (2004)), staring Denzel Washington and Sarita Choudhury, is a story about an inter-racial love affair between Washington and Choudry. Choudry's Hindu parents are portrayed as refugees from Uganda and there are very moving scenes shot in Uganda that depict the pain of the exile.
