I also have a friend who works in the stats department in NYC. Back in 2011, he was getting paid almost 90K salary (not including benefits like you mentioned) and he told me that he loves his job because there's little or no responsibility and is certainly not challenging. He's still at UN and I haven't talked to him in the past couple of years. That and my personal experience interning at NGOs have convinced me that these jobs actually are quite chill and well-paid with little or no actual work (the hard work like field trips are usually delegated to locals, who are paid significantly less than the management, who are usually foreigners).
