Public services and systems are likely to experience increased demand as individuals, households and companies turn to the public sector to provide services they can no longer provide for themselves. Even though the numbers of people requiring services may reduce, the ability of the systems to provide service is likely to be compromised and therefore many delivery systems are unlikely to cope. An example of this is the education sector. There is already evidence of decreasing school enrolment, however, teacher attrition occurring at a faster rate than reduction in demand. It is therefore likely that there will be a severe shortage of teachers in South Africa in the next 5-10 years (Badcock-Walters, 2001 at www.und.ac.za/und/heard).
