It's not even to do with people being on the board or whatever. Some schools concentrate on their sports, and have professional coaches, amazing facilities etc. And these will generally be schools where the people who go there have money, so your good cricketers will continue to be mainly drawn from the middle class.It mattered even in India at least at the time I was in school.. There were a few places which players gravitated to due to the school's history or the school's administration being under somebody who was part of the cricket board. Have seen a couple of my friends who seemed to have some talent move to these schools.
Even Bavuma and Rabada are middle class guys. Ntini is an outlier, coming from a profoundly poor background.
