Enshrining a one party system

Shall we enshrine our one party political system into our constitution? There are views that a two party adversarial system is not good for us. According to who and who shall determine what is good and bad for us? Maybe I should ask who is the 'us'?

And there is also this view that we don't have enough talents to run two good political parties. Really, we are so short of political talents?
