Before we can build anything, we need to get rid of the tics feeding on us. After that there will be years of blaming (much of this will be race based, further dividing our society),  while the hundreds of billions are being permanently  hidden and washed. In the end to "heal the country" , amnesty will be given to most except a scapegoat or two, and everything that has been stolen will remain stolen, people responsible for this and who supported this will live their lives in luxury.
They made this mess and now, we not only get to clean it up (basically this article is blaming our inaction for their crimes) , but they get to keep their spoils. I have yet to see any reasonable amount paid back properly (the little Zuma paid back was a joke).
No, we cannot talk about building anything at the moment while the wrecking ball is still flying.
