Getting paid more than other folks mostly means you are better at interviewing and negotiations. (Or, if you are a lifer, that you are good at your company's promotion process. If your company is sane, that might even imply something about how well you work.)
I don't think shaming or not makes a difference. It's just irrelevant. (Or are people really going to ask for less in their next negotiations because someone on the Internet 'shamed' them? Really?)
