If they continue with such a policy, those Singaporeans, with the ability and means, must consider leaving before their children, especially male child(ren), attain the age of ten.
With respect, SG may lose many of the above average families and children.
As it pertains to the above, if I was a member of the SG govt, I would prefer to do all I can to retain and keep Singaporeans, rather than to attract FT such as those from PRC and India.
In about 25 years, Singapore and the mix of Singaporeans will be very different from the SG I knew 25 to 30 years ago. Rather sad, and for this I put the blame on the materialistic, non caring and non socialist SG govt.
