singaporean jus love to over commit and buy things that is more than what they can afford.. haha no wonder the gov did not feel any impact to really consider to reduce the flat price.
This is because of the nature of housing, which is:
1) a necessity and a luxury at the same time
2) paid over installments, so the impact is not apparent
3) social expectation and perception of housing to status
4) ties to family, familiarity with surroundings, comfort
Let me use an example. Let's say a family of parents and 2 sons. The father last time can well afford to buy a 4-rm flat at Clementi, with single income, and raise the 2 sons and provide for family.
Now, grown up, let's say the elder brother marries early and buys a 4-rm flat in Clementi, near the parents, say about 10 years ago. (when it was still affordable)
Now that prices have risen so much, the younger brother (who married late) is still expected to do the same thing. He is expected to be able to afford the same 4-rm flat with his wife at Clementi, even though prices have risen much higher than since his father's and brother's time. If he go and buy a Punggol or Sengkang flat, the mother and father will not understand why. They won't do the math and say, yah, prices now are so high my younger son cannot afford 4-rm flat in Clementi. They will say eee, why you go and stay so far? Your brother can afford, why you cannot afford leh?
Remember, we are not dealing with pure logic, where you take out calculator and do the math. You are dealing with a social thing, where it's about relatives' opinion, parents' perception, wife's parents demands, etc.
So some pple, when deciding where to buy, will not do the tough math and decide. They will decide based on social norm and expectation.
