South Africa of 60 years ago was a vastly different place than the South Africa of today. The changes are more than the cosmetic ones such as apparel and motor vehicles. Apart from the fact that the black man had to “know his place”, the white community was riven with divisions. Inspite of also being white, the English speaking was discriminated against in terms of the unwritten Afrikaans Affirmative Action Policies.
Much like the current policies, with limited promotion possibilities for English speakers within the Civil Service, they fled the government service in droves. From the majority of Civil Service being English Speaking in 1948, by 1960 it was overwhelmingly Afrikaans speaking.
