No artisans ?
In 10 - 20 years from now who will fix our lights, plumbing, etc...
Who will build actual physical infrastructure.
Society are fixated on IT skills as the way forward but someone needs to keep the power flowing.
The low level stuff is already handled. Builders, electricians and plumbing is handled by one qualified and experienced "foreman" or "the bass" and all the lackeys do the work that is just inspected afterwards as is the South African way as there is little oversight on these matters.
The true need for artisans is in the higher tech areas such as power stations, water sanitation etc, and as the ANC has already shown time and again, they are not worried about this and so it will be left to crumble (what is left anyway).
True that someone needs to keep the power flowing but that will be subsidised by generators or mini plants provided by private companies to fill the gap. There will always be companies that will stay in SA no matter how hard it gets because it will still make economical sense compared to first world countries. Also, many skilled trades people and IT people alike will stay in SA because they will see increases in their value as the pool of qualified/skilled candidates move overseas.
