Too many to list, and I broadly agree with the sentiment of other replies. Being visually aroused, white pussy reflects light and pops. There is the historical piece & expansion of western civilization (social order, classism, chattel slavery, etc.), I think that plays a role. Also globally, white pussy isn’t as abundant as one would think. The last I checked less than 10% of the world’s population. The more we zoom in terms of availability, proximity and so on, it seems that white pussy is a scarce resource. Scarcity drives value, especially if a thing performs as designed, clearly it does!
