Showing salaries would seem to be a way of offering transparency. One worry might be people going for a higher paying role with just that intent.

Why do you think companies might not show salaries?

So that they get to screw over people who don't know what they are actually worth.

Sorry about the relatively-crude language, but I don't know of a better way to put it that's still succinct.

No need to apologise - it's a perfectly justified way of putting it. Could be considered a cynical view, but justified still.

Also, note that employers are seldom as rushed to find an employee as an employee is to find an employer.
