I recently read an interesting sentence, talking about English speech: “Accent is the con-man’s first resource”.
For various historical reasons “accent” has become facet of the English language with identifies people according to their class and education as well as the region they come from.
This is not the case in Spain. There is of course more or less educated speech, meaning variations in grammar or a range of vocabulary, but apart from that, there is no such thing as “class accent”. People of all walks of life and levels of society speak with regional accents without fear of being “labelled” in any other way than being from a certain place. This means there is no need to “put on” accents either, an activity also typical of English speakers.
