I think what the original question referred to before incurring completely pointless assertions of non-existent Singaporean racial equality and an outburst of recycled propaganda, was, that indeed in many professions, including staff of SIA and the airport grounds staff, the Western eye spots much more darker skin than a decade or two ago. I think the answer is simple and has very little to do with egregious policies, it is simple a fact of a formerly discriminated and thus undereducated class moving up the social ladder and filling the posts that (whiter) Chinese are leaving as they move up to the echelons formerly dominated by whites. All in all, it's a sign of progress and the associated social shifts, and I don’t think it's a special airport policy to prepare the airport for Mahatir’s next state visit.
