Did you watch the video? South Africa under apartheid produced more clean water than SA of today, built more asphalt roads annually than today, had higher life expectancy (even in the poor townships) than today and a lot less crime than today.
I was taught in school that most blacks in Townships lacked access to basic amenities. Hmm
I will just give you 2 statistics to contemplate;
The year 1976 SA had 3 murders a day
2016 SA had 51 murders a day on average
Truth is uncomfortable
