It's a great scene, which many interpret as more of a love letter to the city than actual vitriol. By the end, one realizes Ed Norton's character, Monty, is mostly mad at himself.
One can arguably make a similar interpretation of this piece.
Funny, that rant turns into a love letter to New York by the end (Norton is expressing his frustration at what he'll miss when he goes to prison). If this Medium rant has a similar denouement it's even more subtle.
Second most elegant use of fucks, after the Wire scene.
I take it you have not seen "the thick of it" and that's just middle class actors playing a role- I do know people who are the real deal :-)
