One thing I know is and where I live, the first thing on their agenda is the abandoning of their local/ county accents.False social hierarchies. Amazing how some people still believe that as they work on their Dortspeak "accent".
Thankfully the Dort accent is disappearing, but a non identifiable American accent is now the norm.
it's like they are trying to erase their origins.
That's why I think accents are great, they are original, authentic, and unique.
