Funny, and perhaps uniquely Singapore again. People in other countries want to boot out their ministers when property prices fall.
85% of Singapore households already own HDB flats of various sizes. All prices have gone up (or skyrocketed). Who's complaining? Yes, those children of the current flat owners who turned adult and looking for their own flats. If HDB (new and resale) prices fall, they'll also get hit in their parents' networth and bequest. The real problem isn't rising flat prices. The real problem is income level failing to catch up.
Logically, opposition and dissenters should take aim at labour policies insteading of housing policies. But hey, this is Singapore.
