I know a chick from mastic beach that sounds like the rza.Yeah there are still accents but I think the differences are becoming less pronounced. Think of the younger native whites you've met in NYC, do any of them have that exaggerated mafioso type accent that New Yorkers are stereotyped as having? Plus there are a lot of Latinos and Asians that don't ave anything resembling a "classic" NYC accent. Many of the NY born Mexicans, Ecuadorians, and Colombians totally sound like they could be from LA.
I think many Latinos in flyover areas copy slang from hip hop and black social media lol.
Hell if anything, I see people in rural areas laying on southern accents for no reason.
