Different cultures have different standards of beauty.
South Asia have historically favoured lighter skin before even making contact with the west because tanned skin probably means you work in a field like a dirty poor. Parts of the Caribbean favour being fat, because being thin means you're probably a dirty poor.
In fact a lot of cultures standards of beauty boil down to whether or not you look like a dirty poor, because its pretty strongly hardwired into your genetics that you want to fuck something that will keep your bloodline strong.
