The standard seems “better” only because of accident. Dialects are equivalent to subspecies in the animal and plant kingdoms. Scots, Brooklyn English, and Standard English are to “English” as cocker spaniel, dachshund, and collie are to “dog.” Just as there is no “default” or unequivocally “best” dog, there is no “real” dialect of a language. Rather, dialects are evidence of the variety-within-the-variety among the descendants of the first language.
