Chen Show Mao was never a Singaporean to begin with and most Singaporeans are unable to connect the dots as to how a Taiwanese became a resident and citizen of Singapore.
Like the Roades scholarship, for which he took up citizenship only after, he came to Singapore at a time in the mid 80s when the country was already grappling with low Chinese fertility rates. "Chinese grad females not marrying their male counterparts" or "Chinese having the lowest fertility level amongst all races"... while LKY set about to offer $10k to the CPF accounts to the lowly educated mothers (aka Malays) to undergo voluntary sterilization at the time of acute baby shortage, the govt was offering resident status including citizenship to those from Malaysia, Taiwan, China, South Korea, HK, etc, primarily the Confucian stock of which we now have Chen Show Mao.
This fact is not lost on the Malay minority and bound to be a vote loser for WP. [emphasis added] -
