huh?? those sweepers or toilet cleaner dont contribute any less
than those doctor/lawyer to the society leh. If the doctor/ lawyer
dont work for a month, the most the population drop a bit and
criminals gotto wait a month longer for their trials. If the
cleaners dont work for a month, the streets and toilets will be so
dirty that no tourist will wanna come to singapore thus affect
tourism and economic leh....so who contribute more to the
society??
Anyway if what they need is A grade sperm, then just ask the SM and
DPM to contribute to the sperm bank can liao since theirs is so
call the best.
