I think we should not under estimate Ms Chua and her thinking. She is no ordinary journalist. She knows the workings of the government just like Mr Han Fook Kwang who wrote in the same paper urging the government to let resale flats for citizens only just 2 weeks ago.

Their writings about resale HDB flats within a short period of 2 weeks cannot be ignored.
I believe more CM is coming soon to curb prices of resale HDB flats. It could be next week when HDB announces its last sale of BTO flats for the year. Keep your ears wide open.
