Speaking as a white male I am eager and enthusiastic for my minority future.
Depends. If becoming a minority is enough to level the paying field, that would be great. However, I suspect based on, well a lot of history, that "we" will do whatever is necessary to make sure that we still wield majority powers. That I do not look forward to, since we've seen that trailer enough times already ("Jews will not replace us" and the like).
South Africa exists in a world with centralized diffusion of media. I don't think it stands a chance when the overwhelming majority of people under 30 don't read newspapers, don't watch television, don't listen to the radio but have logins on at least three social media platforms. I mean yeah, obviously - rich gonna keep right on richin' but entrenched power structures aren't impervious to floods.
