WOTC - Encourage immigration

I asked this question in the Wisdom of the Crowd:

Should Singapore have a policy to encourage immigration?

Here are the responses: (70 Votes)

46 % - We are already too crowded.
26 % - We can have more people, provided the infrastructure is kept in pace.
19 % - The immigrants will spoil the character of our population.
9 % - We need immigrants to offset the low birth rate. 
1 % - We need a bigger population to sustain the economy.
