Commenting on Malaysia's brain drain to Singapore, SMU Associate Professor of Sociology Alwyn Lim said that Malaysia’s population is “large enough” to mitigate any economic impact from migrating skilled workers. “In that sense, I do not see an economic impact large enough to slow down co-prosperity efforts,” he said, referring to Singapore's and Malaysia's economies’ co-dependence. Assoc Prof Lim, however, noted that the economic contributions of nearly a million Malaysian workers are not insignificant. He also noted that the economic migration is largely positive for Singapore as Singapore’s falling birth rate means it requires more workers from abroad to sustain or accelerate its economy.
