About 100k westerners according to Wikipedia - not a large percentage at all. Now correct me if I'm wrong, but those compounds basically hire their own security and ignore several SA religious laws. SA isn't yet a business-friendly environment for westerners, and that goes twice for Americans. Rather, some westerners are doing business in spite of a hostile environment. I would love to read about your experience and thoughts as someone who's been there, though.
