In the same kind of spirit, when i was the tech team manager in a company without any transparent salary policy, i've been practicing what i've been called the "symmetrical salary management": when I knew the salary of a managed team colleague, i told him/her my salary. I also asked to keep my salary private, as I kept their salaries private.
I think this is a pretty important requirement to build trust in a team.
