Details of money everyone found in career (5,5)
I believe the answer is:
small print
'details' is the definition.
(small print is the details of a contract)
'money everyone found in career' is the wordplay.
'money' becomes 'm' (abbreviation in economics).
'everyone' becomes 'all' (all people).
'found in' is an insertion indicator.
'career' becomes 'sprint' (career can mean to rush or speed out of control).
'm'+'all'='mall'
'mall' going inside 'sprint' is 'SMALL PRINT'.
'of' is the link.
(Other definitions for small print that I've seen before include "Obscure terms" , "You may regret not reading this!" , "Inconspicuous part of agreement" , "Words often ignored" , "Be careful to read this" .)
