Actually its partly true. Since 94 there has been great strides in terms of getting water and electricity out to most people. I saw stats years ago that where actually very good. The issue is that because of infrastructure neglect it all won't matter much soon. Water infrastructure is aging and starting to collapse as is sewrage treatment all over the show. The two are interlinked as when sanitation plants break down the sewrage is just pumped into the local rivers. Bad stuff.
Another related set is our ports/rail/road infrastructure. Our rail network is in very poor condition and is very badly managed. My dad worked on a coal mine in Mpumalanga and they would get perhaps half the transport carriages they requested. Hence they started to have to use the much more expensive form of road transport which accelerated the destruction of the road network. Our ports are also struggling with many of the skilled workers retiring and incompetent people coming in.
Add to that the debacle that is public healthcare, ongoing service delivery strikes, growing unemployment, etc and I am sorry but I can't agree with mr Zuma. The country is in a slow and steady decline towards a failed state scenario. It can still be reversed but it would require honest and competent men in government. There are few within the ANC that meet both those criteria tbh.
