What he is actually saying is that the economy is enough for them. Their surpluses must not be forced to do anything of value to expand the pie. They should rather be used to build public infrastructure, which is quasi gov bond issuance.
Sadly, GNU listens to these idiots.
South Africa must, as a matter of urgency, shift from the current government spending growth model to a savings based private sector investment model. The current model has taken SA into a debt trap and fiscal cliff, as taxes have risen, government spending has risen and growth has languished for almost 2 decades now. The current model is not working. There is also a dearth of examples around the world where this strategy has worked. The investment-driven growth model has many examples around the world which has delivered success including low unemployment and higher wages.
