Room for Improvement? There's always room for improvement for everything else including policies. If that fine-tuning is being made continuously (4 million population to be precise), all the time. I guess the poor MPs, even with their alleged $10K allowance have to set up tents in Parliament Building and work in there 24/7.
Oh, they are Humans as well. With their own Rights amongst the basics to go home & eat, drink, sleep, piss, shit, screw as well as chill-out like everybody else.
Assuming if all 4 million Singaporeans have a degree in economics, each interpretation of text are different (leading to potentially 100 different types of physical test scores) for exams.
Pulling in religion as an analogy, can we guarantee 2 pastors having exactly the same interpretation of a scripture text in a religious book even though the religious book is a standard issue amongst the places of worship?
