According to Miss Manners, it is vulgar to discuss money. I’ve said it before- this attitude is what gets us into financial messes (personal and nationwide). You can’t make a good decision in a vacuum. But if no one discusses finances because it is vulgar or rude, then no one can make an informed decision.
I do not go around telling everyone how much I make or telling people how to manager their money, but if you want to have a conversation about it, I’m game. We have to talk about money if we’re going to make smart money decisions.
