OPINION: Don't compare Singapore pay with other countries? It depends.....

It is okay to compare Singaporean workers' pay with other countries:
"DPM Dr Tony Tan, addressing Sembawang Shipyard workers yesterday cautioned them about the need to cut CPF and wages to make Singapore competitive. He said the independent research unit PERC in its report released confirmed that the labor costs in Singapore are higher than USA and Australia." [Link]

It is not okay to compare Singapore ministers' pay with other countries:
"Singapore’s ministerial salaries are high but should not be compared with that of other countries, Deputy Prime Minister Teo Chee Hean said on Monday. He also explained that the option of benchmarking local ministers’ pay to that of foreign leaders was rejected because salaries at foreign countries may not correlate to Singapore’s situation, and that it was more appropriate to peg ministerial salaries based on local factors."[Link]
