Everyone has an accent

The midwestern accent isn't "no-accent" it's just the most neutral sounding one and this is the one used for boilerplate media (the news, entertainment news, etc), and mid-westerners have tested as being the most averse to hearing anything that doesn't sound like them. The west coast accent strikes people as being too liberal, the New England and Northeast Accents are associated with elitism (upper class) or aggressive (lower class), and the southern accent as unprofessional (upper class) or dumb (lower class).
The mid-west being so big and not associated with any particular lifestyle stereotypes and the really flat vowel sounds make it sort of "basic" english
It's the most boring accent imo
