Interesting thread.
I'm a public employee and so my salary is a matter of public record and I'm open about it. But when it comes to net worth, my husband and I disclose that only to our lawyer and our accountant--we have a pact to tell no one, not even our kids (probably that will change someday, when we are likely closer to the end of the line). Our kids are hard workers, high earners, and good savers and investors--we've always talked values and strategies with them--and that, along with a major investment in their educations--has really paid off, but we don't feel a need to disclose NW numbers.
I WISH I had a friend who enjoyed the same combination of luck and decision-making that have led me to the financial place I'm in, and it would be great to discuss the nitty-gritty, but I don't, and I don't want to brag or sow envy or resentment or depression. Most of my friends are struggling financially for various reasons, ranging from divorce, to a kid in re-hab, to never having found a good career groove, to having chosen a worthy but low-paying path, etc., and they know I'm in a different place but don't know the details. I do enjoy being able to pick up the check or buy a pair of concert tickets and treat a friend to something he/she can't afford, or give a struggling friend's son or daughter a nice gift card to their college bookstore, but I try to do that in a low-key way.
