I have been through the range of experiences to say with 100% confidence that I do not fall in your set of We. So your rule cannot apply universally. Whether I had a very lot or only a little, I have never been one to compare myself materialistically with others and experience feelings of envy.
Don't be so sure. I used to think I never compared myself with others and then I really thought about my frustrations one day and realized I was trying to keep up with or out-do my family and friends. It's far easier to be honest in our opinion of others but not so easy to be honest with ourselves. Our egos prevent us from seeing things like envy which Just prolongs the problem.
