haha~ so suprised there are still some extremely short-sighted singaporeans as you! Now in mainland, companies like google, baidu and hq of local banks offer fresh graduates 10k+CNY per month which is still increasing each year. For lz, don take the job, you will def get one with salary above 2.5k/m and apply for PR after one year. It's so easy to become a singaporean now.
I have several singaporean friends who had a master degree from world top univs with 2 or 3 years of exp, and none of them get salary above 4.5k/m. But plenty of my Chinese friends got great jobs in IBD in London or HK, earning so much higher than here.
