You really are making some silly allegations, bongo. You asked for a concrete example of systemic corruption so I gave you one. Now you want to change the definition.
"You have not provided any example of systemic corruption. What you have shown is a couple of dodgy local councillors picked up by the system."
No bongo, the whole council got sacked. That makes it definitively systemic in that instance.
"You allege that there is a government wide conspiracy to keep immigration numnbers high so that the government mates can profit by 40x times increase in land values."
Nonsense bongo. My contention is that immigration is a major driver for land rezonings. I make no claim about how much profit gets made; that would be specific for each rezoning. Corruption is more about opportunity, not government wide involvement. Immigration provides the opportunity, that is all.
