hdb: 5 equals 4

the latest announcement that hdb is converting its unsold 5 room flats into 2 x 2 room flats is another funny figure crunching. 5 rooms become 2 rooms. the only thing good is that the converted 2 roomers must be technically having 2 and a half room of a 5 room flats. so these flats must be bigger. just like a 5 room flat must be bigger than a 4 room flat. good buy. provided there are buyers. apparently so as the number of buyers for big flats have mostly disappeared and many are downgrading to smaller and smaller flats. so much for prosperity and a booming economy and good times. during good times people are all downgrading. what happens during bad times, all upgrading?
