During 70's, 2 is enough.
Now, not enough, import. But import correctly? Think of a woman, almost 40, convert to citizen. If she is a les, she wouldnt marry n even she is not, she might not n even she might able to, chance for her to give birth is low n she can manage a lot n the kid is only 20 when she is 60!
Future. Due to present situation, more old ppl are generated and the problem never going to be solve unless
Gives out citizenship to new family with kids first. Single over 30, lesser chance. Singapore just like a chinese rojak last time. Now mix with indian rojak, sure LS after eating la. Worse still, add sugar, salt etc into it, can go hospital liao.
