I was shocked, when I came to the Philippines first, at the level of discrimination that exists, not between Filipinos and other ethnicities, but between pale-skinned Filipinos and dark-skinned ones.
Filipino ethnicity is essentially built on a Malay base, but with many later additions. This gives rise to both a hierarchy and a whole industry. The paler one’s skin tone, the more beautiful/handsome one is. This is a universal rule. Extremely beautiful women with spectacular bone structures but dark skin are regarded as less attractive than plain, pale women and the same is true of men. This is true across Asia, but in the Philippines it reaches extreme levels.
