I suspect it’d depend on if things are standardized or not. In my area for example you can tell who are members of old families and if they were raised by roughly boomers or older, the reason is that those of us that were generally have old or even archaic accents. Gen X to roughly middle millennials don’t have the accent at all since they apparently the schools were overly standardized and treated it like a speech impediment, because the new blood think if ya dlnr sound like youre from LA then youre speaking wrong.

Also if you are curious what I have accent wise, some bastardized Scots accent not a brouge though closer to whatever the fuck regional accent Lazerpig has.
