Does a Malaysian's salary will always lower than Singaporean's salary? As a degree holder, my pays are even lower than poly's holder. Is this true?

It all comes down to standard of living between the countries. While SG salaries are relatively higher, you have to take into account the costs of living in SG compared to MY or BN.

It is not true that malaysian salary will always be lower than singaporean salary. But it is true that malaysians are willing to take less salary compared to singapore on the same job, because of the x3 factor. cost of living for the household for a malaysian supporting family in malaysia vs the same settings in singapore paints the picture quite clearly.
