 The new policy took into account Singapore's falling fertility rate and its increased proportion of the elderly, but was still concerned with the "disproportionate procreation" of the educated versus the uneducated, and discouraged having more than two children if the couple did not have sufficient income, to minimise the amount of welfare aid spent on such families.The government also relaxed its immigration policies.In October 1987, future Prime Minister Lee Hsien Loong, then a young Brigadier-General, exhorted Singaporeans to procreate rather than "passively watch ourselves going extinct".
