Is it wrong for a person to change their accent?

I agree with aspects of both points, I believe that convergence of accents is essential for different situations, you would not go to a job interview with an accent you use around your friends, you would try and sound more sophisticated. Also I believe living in a different country you will unconsciously pick up their accent especially if you are trying to learn their language. However I don't believe that any accent show lower class or that people should be judged on how they say something rather than what they say.
