Control working and income (9)
I believe the answer is:
dominance
'control' is the definition.
(synonyms)
'working and income' is the wordplay.
'working' is an anagram indicator.
'and'+'income'='andincome'
'andincome' anagrammed gives 'DOMINANCE'.
(Other definitions for dominance that I've seen before include "Influence (over others)" , "top position" , "Ascendancy" , "Commanding position" , "Supremacy" .)
