I wasn't a down voter, but I understand their sentiment with respect to your comment.

You being ambivalent suggests that you're okay with less informed people being screwed. I think that's grossly unfair on a bunch of people, especially the highly technical folk that can't bullshit their way to a good pay packet, despite being technically capable. Keeping salaries open is a good thing in my opinion. The fact that companies at times will discipline employees for discussing salaries should make you see that it's a bit of smoke and mirrors used by managers to screw people, while paying themselves handsomely. It's total rubbish, and quite frankly does more harm than good.
