I read your sentence as one talking about the endpoint of singapore politics - whether a two-party system or a multi-party system is better for singapore.
My own perspective concentrates on the starting point of singapore politics. Today some had made a case that there is a two-party system in Singapore - the PAP and WP. Others with equal justification will say that there is a multi-party system in Singapore, counting in SDA, NSP and Gopalan.
The point is whichever way you look at them, the bottom-line is that they are ineffective. On the one hand they will say the PAP is unfair. On the other hand, they are not prepared to engage in new techniques, allow new leadership to emerge that can make the PAP tremble.
Many of the things they said are not without justification.
What is without justification is the repetition of the same old techniques that led them nowhere in the past.
Thus the starting point of singapore's politics should be the emergence of a new generation of leaders. The hope therefore lies in the single seat wards whereby independents can emerge without the need of affilating to any party.
Salvation lies not in the established parties. It lies in the emergence of new talent.
