Here is a particularly interesting one from there 
Let's think of the quite pausible scenario in which our nation
birth rate could not substain our manpower needs for national
service. With respect to tripwire's suggestion, one should note
that monetary benifits are no longer a carrot to our womenfolk.
With the 3 years headstart, they can earn well enough to cover it.
Furthermore, if they opt not to have children, the income they gain
will far exceed what they get from those bonuses that the
government offers.
We should view this problem in a different light. The carrot
approach has shown to produce dismaying results and there is no
reason why one should continue in this manner. Bonus can still be
used as an incentive but with a twist. Our womenfolk should be made
to sign a clause at the age of 18 having the following
conditions:
1) If she wants to be exempted from NS, she has to bear a minimium
of 2 children {to satisfy the minimum statistics to ensure a stable
popultation growth} by the age of 35. {To lower the chance of Down
Syndrom }
2) In the event that she does not fufill this clause by the maximum
age, she has to pay out an amount equalvalent to 35% of her total
assets as a donation to various charities. Failure to do so will
result in pausible legal action against her and her immediate
family.
3) In the event that she could not get a husband or any other means
to gain children, there will be 2 options left
i) age : 25 < age < 34
She has to sign up for compulsory National service, or opt for
artificial means to produce children
ii) age : age >= 35
Apply condition (1) to her.
3) If she chooses to immigrate or take PR somewhere else, she has
to deposit an amount up to S$500,000 with the government. Failure
to satisfy conditions (1) and (2) will result in the S$500,000
being donated to charities.
Of course for those women who bears children, the baby bonus still
applies.
Let's face it. We will be in dire straits if we do not take drastic
measures. As Machiavelli said, the end justifies the means. We need
to, above all else, ensure our survival for the
future.
