You being a highly paid member of the publisher's staff (4,6)

'a highly paid member of the publisher's staff' is the definition.
I know nothing about this answer so I can't judge whether it can be defined by this definition.

'you being' is the wordplay.
I cannot really see how this works, but
'you' could be 'reader' (I've seen this before) and 'reader' is found within the answer.
'being' could be 'dear' (dear is a kind of being) and 'dear' is located in the answer.
No letters remain.
This explanation may well be incorrect...

Can you help me to learn more?
