I get access to salary statistics every year via my union. They collect everything from the member, support is almost always around 80%. Just plug in area, experience, title and if you have a management role. So yeah, my answer would be: most people have insight in salary levels. Also remember that in some countries you income is public record that can be looked up by anyone.
