Hard disagree. (Heads up, gonna get real language wonk here.) American English is actually based off English peasant pronunciations. The whole modern British accents crap is actualy a late 19th century phenominon that was intended to replicate social caste systems by enforcing stupid cultural boarding school pronunciations. Yeah, really, look it up! American English is more akin to English as it was originally spoken. Most American immigrants were the undesirables of European society. Before there was American imperialism, there was British imperialism and, while fuck 'em both, I’m gonna stick with the historical pronunciation of the working class.
