Basically, the standard dialect is the prestigious one. It's the one that people are encouraged to speak. It makes one sound educated and well-off. Nonstandard dialects are equally valid forms of communication. They are no more or less complex than the standard dialect. They are spoken and understood by equally educated people. In some ways, nonstandard dialects can be more "regular" than the standard dialect, or may express certain ideas better. In other ways, the standard dialect comes out ahead. While there are right and wrong places for any language choice (Klingon is a fine language, but there's no good from speaking it at most weddings, AAVE will probably not get you a job as an English professor, and so on) the languages and dialects themselves are not wrong.
Unless, of course, you choose to view French and Spanish as merely incorrect Latin. If that's how you view the world, far be it from me to interfere.
