I disagree with the idea of changing the one-man-one-vote system into one that gives two votes to certain groups ("A more equal voting system needed in greying Singapore"; Wednesday).

Once this principle is established, where will it end? It will open Pandora's box. We could begin our slide down the slippery slope with the following scenarios.

Should those who pay more income tax get more votes? Should those who are more highly educated - for example, professors and academics - get more votes?

Should votes be based on gender? Should men be given more votes, presumably because they are stronger and can work harder?

The danger and the problems of the argument become more obvious when we consider: Who will decide on the issue?

Let us not tinker with the equality that the one-man-one -vote system brings.
