Perhaps one fundamental difference is that BA, Emirates, Cathay and Lufthansa might select their cadets on the basis of a structured and proven capability profile. Some might be concerned that SAA, the state airline of a country where advancement within the state employee market is already determined almost entirely by the colour of one's skin, is using racial bias as its employment criteria. Were that true, aviation safety might be compromised as candidates were advanced within the state airline to positions based not upon their ability but rather upon the accident and privilege of their birth.
