I have visited NYC a few times now and I sincerely hope you don't consider the native speech there to be representative of proper American English. It's a weird and extremely grating nasal abomination punctuated by such erudite phrases as "you douchebag, ya scumbag".
Picking that region and main newspaper for some "lesson" in proper speech is weird. It's completely alien to the rest of the nation. It really should be its own city state, I would be thrilled if they removed themselves from the US actually, or they were asked to just leave, and take their newspapers and so called financial "industry"-the white shoe boys gangster mafia-with them.
The New York Times does not publish in the dialect(s) of the common citizens of that New York City. It has been regarded as a "paper of record" for most of its existence and is more formal about adhering to an academic writing style than most other newspapers.
