In 1976 Parklands and Century City didn't exist. What's your point apart from being prejudiced? Population growth and migration are facts of of human development since the dawn of time but it appears bigots, who're always noting Eastern Cape 'refugees' and the expansion of black suburbs, don't understand or won't accept this fact. 
For those who don't go there, areas like Table View, Parklands, Century City, Somerset West, etc are like another city, so has it expanded within the last 15 years, never mind 30, much of it new. Are you saying residents of CT's old suburbs - before these new white (and black) ones - should resent ALL relative newcomers. (Where do YOU live btw?) Get over it!
In 2006 a city water engineer told me new developments were straining the city's water and sanitation capacity. I'm tired of ignorant comments blaming the DA's incompetence on others. I value freedom of speech but sometimes it's a pain having to hear/read the rubbish, on all sides.
