Like I said before, you are the one talking big about "fighting" LKY/PAPs, "fighting corruption", "fighting incompetent governance", being "practical and realistic" etc, so what is your "practical realistic" model of governance?
You have thus far failed to provide any, so why should anyone pay attention to you in the first place?
As for me purportedly having "no answer", again I am not the one desperately seeking publicity, you are, accordingly it is incumbent upon you not me to explain yourself.
However since you keep asking for my "answer", without any basis I should add, I shall oblige you with a brief sketch.
Go read Joseph Schumpeter for the general ideology.
As for the practical nuts and bolts way forward, I see a PAP split after LKY passes away and when I say PAP split I am not just talking about PAP political party itself but the entire Establishment Elites across all sectors of Singapore society. As to how long long this shall take after LKY passes on, who knows for sure, but I think within a time frame of 10-15 years is a possibility. Transition shall be messy (change inevitably brings about messiness and uncertainty) but by this time probably manageable so as not to foresake national stability both security and the economy. Singaporean Generations X, Y, Z and beyond should probably be much better educated and more globally exposed through eduction, travel, work and the net to act rationally with general reasonable political maturity.
Barring unforeseen drastic extreme circumstances, the large majority of Singaporeans shall probably never give credence to a 'revolutionary reform movement' to oust the PAPs from political power because rationally the negatives appear to far far out way the benefits, and rightly so I should add.
Btw I have not ruled out the PAP government in power going the dark route if its power is really truly challenged by say a PAP split using methods like martial law, vote rigging etc. However if it does indeed go down this dark route, then it is definitely the start of the end of the PAP government because this would rationally justify the rise of a 'revolutionary/reform movement' which would eventually succeeed in ousting PAP going by history. However in this worst case scenario Singapore shall probably be left in ruins and rubble, so I don't think the PAPs would take this dark destructive route. Afterall Singapore has already moved beyond a banana republic.
Finally sorry to burst your bubble, but if you are really truthful, practical and realistic, it is highly unlikely that the political status quo in Singapore shall radically change while LKY is still alive and active in the political scene. The ground reality appears to support what I say. There still appears to be quite alot of 'fat' around to spread about and the PAPs may appear to be cold, arrogant, harsh, mean, stingy and greedy but generally they are not stupid and not corrupt in the traditional sense. Unlikely that PAPs would actually cross the political 'red line' while LKY is still around.
