No one can predict what is going to happen, but the projection is there will be continued growth. And there is confidence in this, just look at what's happening next to Changi Airport, they're building a new one! Regionally, the mood is upswing, despite the poor showing of the ringgit, the rupiah, the baht, the peso, ASEAN is braced for growth. And Singapore is smacked in the middle. This all will keep rolling as long as there is peace.
I do not know what to say about the crowdedness and congestion in Singapore though. It really sucks, but I suppose people will look to the leadership to work this out (if they can.)
Cheers!
