For this reason I'm also selfishly for not publishing salaries within a company.

I'm all for talking about salary to everyone except co-workers. Knowing what you can make elsewhere gives you power to negotiate or move. I know what my engineering friends make, I know what they are getting bumped to after reviews, I know what offers they are getting and the same goes both ways. Knowing what everyone makes internally would just cause trouble I think.. At the least I would imagine it would limit my options to only companies that can afford to pay everyone top dollar..
