Arguably, the frequency of malapropisms in the boardroom suggests economic mobility is taking place. The vernacular of those in the socioeconomic class that someone of a lower socioeconomic class aspires to join will be unfamiliar.

Clumsy expressions of socioeconomic aspirations go beyond language, of course. Take the infamously bad taste of the parvenu and the comical snobbery of the nouveau riche and those who ape them.

Kinda like some HN posters write the way they think academics talk?

Best comment here, and even made me change my perspective. I have a work colleague that makes a lot of grammar mistakes. It annoys me but I'm wrong. Funny mistakes everyone makes, but we must be careful with our prejudices. Thanks.
