Do you earn what you actually deserve? Personally i think that Malaysians earn way below the right remuneration. In an economy like ours, i think that we should be brought to be in line to the correct pay scale considering the cost of living is not exactly cheap in this part of the world.
Found this pretty neat website, payscale.com that you can use by answering a set of simple questions about your current job and it will tell you how much you are earning in comparison of what the industry standard is. You can can also view what ratio of the population is earning for the same job and trust me, you are going to be shocked.
The website has some cool tools like the Cost of Living Calculator & Career Path Tool . Highly recommend you check it out and be prepared to be pissed off!
