I don't want anyone but my closest of friends to have any idea as to what I make for a living. How do I benefit from that? Now when we go out to dinner, or to buy drinks, is this acquaintance that I see a few times a month going to pressure or guilt me into paying for things? Are they going to be upset that I spent $20 on a birthday present when I make 2-5x their pay? It shouldn't even be a consideration unless I want it to be. Are they going to talk behind my back about how I only tip $1 on drinks but make XYZ amount of money? When people know you're making money they come out of the woodwork and do things they wouldn't do if they had no idea. I'd rather it not even be a consideration in our relationship as friends/family/whatever.
