Explain what the south african government is doing to promote equal access to basic services​
Mumz [18]

Answer:

All they are doing is redistribution, not creation. They are enforcing fewer and fewer people to subsidise and pay for more and more people who do not pay for services. Meanwhile the service infrastructure is ageing and in the process of collapse as it was never designed for so many people, Lack of upgrade and maintenance is the last nail in the coffin.

Redistribution does not work. If you tax people more and more they will stop using the service and find alternatives. Look how many people are going off-grid. I am off grid. It now works out cheaper, I don’t have to suffer load shedding and water cutoffs, and I dont have to pay more and more and subsidise more and more people for less and less service. I don’t care anymore about their loadshedding and huge tariff hikes. The more they charge the faster I pay off my off grid system.

Because they insist on subsidising so many people, there is no money left for capital infrastructure. Policies that drive people off grid means that less and less of those prepared to pay are now contributing to as service they no longer want any part of.

The ANC has only themselves to blame for the utter collapse. Their policies, incompetence, cadre deployment of incompetents to government have brought about ruin. Apartheid left them functioning infrastructure that did well to last until now, well past the design life, and a well run efficient civil service. It shows how good their build quality and plans were. The stuff put in by ANC BEE contractors lasts as long as a Made in China product. All they have done is given equal access to less and less so you have access to a failing collapsing product with no hope of salvation unless EVERYONE pays a fair price by what they use, and the ANC stops stealing that revenue. To expect them to stop stealing is like asking a cow to stop eating grass. It is their nature to graze on the veld maintained by others, not to grow anything themselves.
