This is pretty accurate. I know a guy professionally worth probably $100M. His name occasionally turns up in industry rags, and even in more mainstream business news once or twice. However no photos have ever appeared in the stories. The only photo I can find of him online is his LinkedIn photo. Within the industry his name can open doors, but out in public no one would recognize him and he can live a normal (extraordinarily wealthy) life.
