I could either write a twenty page essay here, or simply post the quote, below, from the SouthAfricanDiaspora blog and express my heartfelt wish to see people and money some day flowing in the opposite direction.
A skilled worker is one of the most valuable members of any society and represents a significant investment of time, money and training. A skilled worker can create on average 10 jobs for unskilled labourers (so I have heard). Only fair that countries would want to attract them. But where are they attracting them from? Someone told me that 20 000 skilled people left Africa last year. … A three year degree at Wits will cost the student about R40 000. The true cost is probably 10 times that. … That is just the tertiary education portion, what about the 12 years of primary and high school before that? Even if we take the very low amount of R1 million per person, that means at least R20 billion was lost by Africa last year. That is R20 billion that was spent by Africa on its future that will now not be part of Africa’s future, but America’s future. $3 billion a year. And that is just the direct cost. If you estimate that each person would have had an income of R100 000 a year (another very low estimate), that is R2 billion a year in lost GDP. If you include the 10 unskilled workers that each person would have employed, it is probably another R2 billion a year. $3.5 billion a year in total. I am sure you have got the point now, each skilled person represents a massive loss to the country losing them and a massive gain to the country gaining them. Immigration of skilled labour where the flows in either direction are fairly equal or where there is a genuine surplus in a country make sense, but when that flow is in one direction it can be disastrous.
So taking this from America’s point of view, they can basically pick and chose who they want from Africa’s talent pool, not have to pay a cent for their education and training, and have no trouble getting them to immigrate. What a great system. Africa, why are you so poor and stupid?
