[...] says it would be great to reach the point where designers and advertisers do not think about ethnicity when they cast a model; where they would cast a Chinese girl simply because she’s beautiful – not because it’s to sell a collection of cheongsam dresses.
Human beings' bias towards beauty is understandable, but it is nevertheless unjustified. From an evolutionary perspective, beauty is a surrogate indicator for health, and individuals in any species have always looked for healthy partners to mate with. Such behaviour leads to optimal results for the species as a whole. However, human society is more than just a group of animals impelled by evolutionary forces. We do not believe in the survival of the fittest. We believe in giving everyone a fair go, with social safety nets for the weakest. We do not let our weakest offspring die. We give them special attention and help. The value of beauty as an evolutionarily favourable trait should be correspondingly lower in a society of human beings.
