It's not possible to run a functioning country (which SA undeniably is) without a large number of people who are at least somewhat competent, at least somewhat hardworking, and at least somewhat loyal to the country. You may be able to rely on cheap migrant workers for the hard physical labor, but not for the planning and administration that makes the whole thing work.
