South Africans rush home on the wave of global financial crisis?

So according to a report that "South Africans are flocking home", many people are returning to the country, due to hard times overseas.
Apparently a non-profit organisation that encourages & helps South Africans to return home, held an expo in London last month where "four out of five" of the +1000 that attended, were returning home within "the next six months".
Oddly enough, I know of people still moving there, as well as a number of individuals who have no intention of returning home.
Fish-packing in a smelly factory in Scotland is still more profitable for many people than working back at home.
I also wonder how many of those people were individuals whose working visas are about to expire or people who have been working arb jobs such as bartendering & nightclub security. Everyone I know that has a professional job is still sticking it out in the UK, even those that are between jobs...
