This question touches deeply on numerous topics, but I would say the foremost areas of concern are your identity/self-image and what you value in life. It sounds ultra cliched, but if you value success solely by income then you are likely doomed to run the hedonic treadmill and will forever unhappily compare yourself to others. American culture does not really have a framework for other modes of living, which is why so many people fall into the 'income comparison trap.' You can spend months/years/decades delving into this question, but as a starter I would recommend checking out Eckhart Tolle's book, "The Power of Now." I don't recommend many books on spirituality since most of them are full of pseudo-scientific garbage, but PoN is a good one for the practical mindfulness tips it gives. I would respectfully not recommend that you move to a lower income community just so you can be the top earner; this is merely putting a band-aid on the problem, and from a practical standpoint your neighbors will likely be less able to help you personally/professionally.
