Since its launch at the end of 1994, the sandwich-class housing scheme has come under criticism.
Beneficiaries of the scheme have thrown their weight behind the project, which was introduced to help middle-class households achieve home ownership.
The idea of subsidising people having difficulty in buying flats in the private sector because of spiralling prices is not bad.
However, the problem is how to define the so-called sandwich class and whether the Government is over-subsidising.
Under the existing Government definition, those earning a monthly household income of $30,001 to $60,000 are classified as sandwich class.
These families also can choose to use the sandwich-class housing loan, with a maximum of $550,000, to purchase private-sector flats.
Critics questioned the need to subsidise families with a monthly income of up to $60,000.
