Exactly.
I used to work in an industry where I met a lot of wealthy clients. I would say there are more unhappy wealthy folks than in the general population. They are overworked, overambitious, highly driven people. Their kids are frequently screwed up from money they didn't earn, and the high expectations placed upon them. They are sacrificing a large part of their life to get where they are. Those are the corporate titans.
Old money folks got it from their parents. Whole different dynamic.
A little money gives you comfort, security, and allows you to enjoy your leisure time. A lot of money does NOT improve this. Sure, it lets you drive a Ferrari instead of a Mustang. Are you really going to have that much more fun in the Ferrari driving to the hardware store, or do you just want the ego boost?
Don't begrudge ANYONE the choices they made in life. Those choices all have trade-offs, you just might not see them, but they are still there.
Find your happiness within yourself. Achieve your own goals, balance your work and family, learn to love unconditionally. Happiness won't come from envy, not ever, and you are not in a position to understand what the subject of your envy lives with day to day. Seeking to regulate or legislate the subject of your envy never results in good legislation, because it is based on envy, not good policy.
Let it go.
And by the way, to twopints: There is usually very little difference between what someone negotiates and what they are worth. No one, no company, no board of directors, doesn't like getting their money's worth.
