All the ideas shared are spot on on what can be done to improve it all, I agree.

However ... I am a wee bit pessimistic.

How to implement all these good ideas, how to get them working consistently, as education is wot, a 20(?), year plan. So multiple presidencies, no?
Job creation, infrastructure upgrades ... decades.

As good as the success stories are out there, and there are, a lot, we, the majority, have become irrelevant.

Let me explain, illustrate, non factual, authors freedom: How many people actually vote in SA?
Wikipedia says in 2014 there where 18,5mil valid votes and 252 000 spoilt votes.
Total votes cast was 18,75 mil votes
Registered Voters: 25,4 mil
Total population: +-54-56 mil people.

So less than half of SA votes. (Are u/18 the 50%, illegal immigrants?)
And of that half a few mil more than actually half voted.
With more and more non-deliverance from political parties, those voters may become even less.

To fix the problem we need a leader/s that can pull this nation together, the majority votes, under one flag, as one nation ... s[he] will have to be a "super hero", for divisive (as a nation) we stand.

So get a leader, the rest will follow, and together we WILL sort it all out.
