I'm not 100% sure, because I haven't lived it, but I'm pretty sure I don't need that much. I like quiet and space, the city's not for me. I need a very quiet property quite far from the hustle and bustle (and goddamn leafblowers!). Also a couple of thousand per year for gadgets/technology. I'm a people person but I hate the fakeness and superficial contact with people that seems to come with jobs in the city ("how are you today?" grrrr), so I feel like a sour puss most of the time, which is actually not my personality so it feels dissonant.
At the end of the day I've just kept the machine running for another day. I work in an important industry, so my job is indirectly important, but I can't ever point to a physical thing that I've created or a particular person that I've helped, and most people don't even understand what I have achieved. I think that makes me feel a bit empty. It's just other people's problems all day with a lot of irritating bureaucracy and "professionalism" but a bag of money attached.
Maybe I'm just lazy but I don't want to work as some people seem to. I have many hobbies that could easily occupy all my time, so I don't feel I need work to be happy. I have heard about studies that say that people are happier working but I really don't think that I am (or maybe I just haven't found the work that makes me happy yet).
Unfortunately I haven't worked out how to make an income away from the city yet, but I have thought about quitting and getting any menial job I can find in the country because the rents are cheap in rural areas. Just can't bring myself to pull the trigger, my current job has a lot of pluses and good pay, and I'm not sure if I could come back to the IT industry if I did ever want to after leaving and getting behind.
But who knows? Maybe after a couple of years with a quiet rural lifestyle I'd miss the city. I don't think so though...
