During the January 27 HDB Dialogue session, Minister Mentor Lee Kuan Yew had said, "It was not an experiment... It was force majeure. We inflicted it on the people, we knew it would work, we knew it would be uncomfortable", and this statement alone is enough to calculate the impact of ethnic quotas on the country.

The topic of foreigner enclaves across Singapore's public housing estate has been gathering rapid momentum since about the mid of 2009.

In January this year, Minister Kuan Yew was asked if there were ay chances that new Singaporeans would be made a part of the Ethnic Integration Policy and the ethnic quotas in the public housing estates.

The answer was, however, received on Friday, when the Government announced that there would be an extension to the quotas to include the country's permanent residents as well.

With the announcement, experts have raised two concerns - first, that permanent residents might just be out-bidding Singaporeans for resale of properties, and second, that the residential properties, particularly flats, are being marketed based on how they would appeal to people of certain nationalities.
