Here's a serious video.
And here's a not so serious video.
I don't sense that Singapore is that desperate yet. Yes, the birthrate numbers are incredibly bad. But until I see some policy changes, I can't say that Singapore is serious enough to tackle the problem.
For goodness sakes, start with making housing prices affordable. Sell them at a profit over cost, sure, but don't peg it to the market. If buyers want to resell their flats, have them sell back to HDB at the same price.
If you have more money to spend on a larger home, then it's more likely to have more children. Heck, you'll even have more time to spend on them too because you won't be so busy working for money to pay off your HDB debt. I just went to a friend's new home and it wasn't big considering the price. If it were me, I'll not have more than one children given the space. Never.
In the meantime, keep making videos and websites. I'm sure they will have a great return on investment.
