One of the biggest expenses in "growth" is infrastructure. Especially from guavamints pocket.
If a large house in Sandton is demolished and a block of flats with 200 units built in its place, the cost of that is paid by the developers, and then, in turn, by the buyers of the units.
This process creates jobs, and the entire process is "growth". Guavamint has contributed almost zero to this venture.
The real money in this project is the infrastructure. Can the roads support an additional 199 families (NO), can the sewage support them (NO), can the electricity grid support them (NO), can the water supply support them (NO).
This so called "growth" is a fallacy. And we are now starting to see that.
