SA has no technology. Its people cannot produce even a screw driver, a pin or a match box. They sell oil and beg the European and American company to build roads and other infrastructures.Promises promises !
Even if SA wants to invest to build an oil refinery, it will ask Europeans to do100% of the entire works on its behalf. So, why should we expect an investment from a totally ignorant group of people? They are just incapable to do anything on their own.
Money investment must be supported by technological investment and SA people are fully a group of ignorant.
