I don't see the term 'Caucasian' mentioned anywhere in the paragraph you quoted. What exactly is 'Caucasian' anyway? The term is often incorrectly applied to anyone that isn't immediately identifiable as African, Asian, or some other distinct race/nationality. 

Light beige or pink skin does not automatically make someone Caucasian, which isn't even a distinct race anymore.

And there are many non-Caucasian characters in the various stores.

In terms of base figures, there are at least 15 to 20 that I can think of right now that are clearly non-Caucasian. Why vendors choose not to develop for them is a question you would need to ask each of those vendors. 

A blank slate figure is not Caucasian, it's a blank slate.
