I believe the rate is rather accurate,but the reason most of us feel overstated is that we are paid as undergraduate. I do see people taken much higher pay. so the average should be true. hehe...heard one of professor moved to the banking indurstry with starting salary like 100k++(USD)...hehe...still could classified as 1-3 years. And some Master Students did get a better pay. anyway, if you feel you are underpaied, just need to make a noise to your boss, see whether he fire your or you fire him...hahaha... even at underpaid rate, the amount is enough for you to enjoy life lah....
life is a struggle
but i enjoy struggling
