Dear Nelstar,
You have asked a very valid yet very simple, critical
question:
"Do you really think remaking PAP will solve Singapore's
problem?"
Yes, I do believe so simply because they are running the govt at
the moment! 
Innovative Economy is managed through a "holistic" approach, not a
passive "reactive" approach as demonstrated by PAP....no jobs? Cut
wages and CPF. Any man could come to that conclusion! But whether
such conclusion is EFFECTIVE to solve the ROOT problem, is another
matter.
Thus, if PAP is not remaking itself into a party that could
possibly grasp the Holistic view and way of management, then it
simply cannot deliver what Singapore needs most right now. And the
fact that it is running the govt, it affects the whole attitude of
civil service from top down.
You ask:
"Why political reform when you have elections? If we need to have
political reforms each time the Government needs revamping, we
should throw elections out of the window"
Now, you are mixing up the govt with political structure. Though
they are not mutually exclusive, but they have distinctive roles.
If you read the article on "The need for Political Innovation", you
would realize that the structure of political discourse and debates
is very different. Diversity is the most important assets for such
things to evolve. The communication between the Govt and the
parliament works both ways, not one way. Robust political debates
are carried out in an inclusive manner, to look at all possible
aspects of the problems raised. Parliament is NOT treated as merely
a "Rubber Stamp" for passing the various bills, policies, laws and
budget, but as a place for robust debates on various issues.
And a monopoly of power by a single party is detrimental to such
robust process which need diversity in competition of ideas. And to
be "inclusive" in its approach, it is inevitable that a
proportionate representation system should be setup. This has
nothing to do with the govt, so far, but rather, the political
process in which the representation of the social segments are
being included.
I don't think Workers' Party is not doing its job in making itself
"stronger", whatever that means. It is interesting you think that
way that opposition parties shouldn't "criticise" PAP..
It is just like talking to a "perceived" weaker contester
in a boxing match that you should not punch the big guys and you
should just go on defence. 
More interesting enough is that why do you think I have the
ability, if I am that weak, to "bring down" the "LEADING" political
party PAP in the very first place?
I think that's pretty irrational; strong guy doesn't just
drop dead like that. And I don't think I am in any ways "bringing
down" PAP; it is just like training a dog or getting a horse to run
faster. You don't "kill" them, but yet, you need to exercise stick
on them to make them do better. If you couldn't differentiate about
that, it is not my problem. 
And besides, nothing is permanent. PAP may be the "leading"
political party now, but that's not a divine status.
If it is not careful and anti-progressive, I think it
will just collapse one day, sadly, with Singapore together.
