My wife and I moved into a decent (new) neighborhood 4 years ago. All new homes, some even on the water at a pretty decent price. One new friend was from NY and had a good job as an FI at a luxury car dealer. He made a good 6 figure salary most of his life. Another neighbor is a PHD (in law), advised billionaires how to invest thier $$. He also owned a large pool company, and seemed to be a high dollar individual. I seldom discuss my finances, but I felt comfortable discussing my finances with these people. Having sold 2 companies, (one recently), my investments far exceeded theirs. It does not serve you well to share your finances.
Also, watch Jordon Peterson on Youtube, he advises never to discuss finances when you are older. Especially to your children, or step children. You may think you are helping them by telling them to not worry about their future, but it changes the dynamics of the relationship. They may start looking at you as a checkbook and may ask for advances on their inheritence, for example.
We are going to be moving in a couple years, and when we do, my finances will be kept the utmost secret. Lesson learned.
