No it's actually the opposite effect, at least for implanted "New Yorkers" both hipster and non hipster alike. Time spent living in NYC actually amplifies *****ey like qualities dramatically. For the non hipsters here for work, the snobbery of dealing with upper echelon manhattanites becomes almost reflex for survival. They say Fake it til you make it and they definitely do.
And for the hipster persona coming to NYC allows them to fully express their inner weirdo and spread their *****y wings. Doing the hip stuff they wanted to do when they were living in their small town would get them beat up, wedgied then stuffed in their locker. Now doing those things gets them labelled "creative" and "unique" by other useless humans with no real worries or responsibilities. NYC is no longer the rough and tough inner city it was. It is now a haven for all the wealthy rejects from everywhere else to come live in a **** hole loft in Brooklyn for $4300 a month, live off of their disappointed parents success and wealth and become smelly artists. Raising rent and inflating the prices of all products so badly that normal hardworking blue and white collar families can't afford to live in the neighborhoods they, and their parents were raised in.
There's my rant for the day. I need a drink!
