The extract illustrates the difficult societal circumstances and conflicts which were created by a legalized system of oppression. In the first place, whites, in terms of the apartheid system were placed in superior position and could play a part in all the privileges such a system granted them.

Their actions were not essentially guided by sense of obligatory duty or pity but they felt being superior meaning that they could be patronized and make available for those in need. Furthermore, because of the huge difference, the less privileged classes were required into subservient positions and this led to manipulation and abuse that survival became a anxious struggle.
