Not to be daft, but I can't imagine a single reason this is better for you career or labor organization-wise. If anything, it strikes me like that old quote:

Benjamin Franklin said: "Those who would give up essential Liberty, to purchase a little temporary Safety, deserve neither Liberty nor Safety."

Not knowing the wages of those around you makes collective organization and bartering harder which is bad for workers in aggregate.

I agree but because I don't think those at the top would ever let the transparency be complete. Unless the company was started that way and managed to keep it while growing. Which experience seems to show is hard or unlikely.
