You see, now you are trying to siam the question and smoke everyone again by trying to change the point of focus to privacy. Gay Loong is a public figure and he claims like you claim that there is no corruption and everything is transparent. As a public figure, he has no privacy. He can't avoid the public in his profession. And he is on Facebook, and updates his FB regularly, that's hardly a sign that the man is a privacy avoiding hermit. You on the other hand, no one cares about. SO, what you earn is irrelevant. What Gay Loong earns on the other hand is very relevant.
The public definitely wants to know how much bonus one Minister got over another Minister. Why? The public does not want to see poor performing Ministers rewarded. The Transportation Minister should be getting less bonus due to all the MRT breakdowns and what not. This is real life. In the corporate world (WHich the PAP base their salaries on), poor performance results in termination, and most certainly demotion and less pay. The public wants to see this process of lesser pay for poorer performanced confirmed. How do they get confirmation when nothing is revealed about their actual dollar pay and salary? Get it?
