In my experience, employers are not particularly happy when you do this kind of thing. I can't tell you for sure, but my assumption is it's make them feel weak or helpless & the last thing they want is to seem like that, especially to a key employee. Maybe find a more subtle way to push this, but being very direct (for me) has only ended up with an employer who is upset that I know my role is delivering 5-7x my salary.
