This whole comment seems like a charming case of advanced Dunning-Kruger. You sound very confident in your assessment, but then it seems you are honestly suggesting that NYC TRACON controllers are being inefficient on purpose… for what? Fun times? You said it yourself— it is a busier airspace. The approach and departure spacing of EWR, JFK, LGA and TEB— not to mention the changeable airspace restrictions over parts of NYC itself and managing GA traffic into and out of the Hudson River Corridor— makes a simple single hundred mile long elephant walk to your preferred runway at JFK logistically untenable. Not to mention potential conflicting traffic from smaller airports in Connecticut and Long Island… And just a gentle reminder that as pilot in that airspace you have precisely one small piece of the big picture when it comes to being aware of exactly how complicated that can be for the ATC personal.
