He does nothing to hurt industry (7)
I believe the answer is:
striker
'he does nothing to hurt industry' is the definition.
The answer is a person as well as being a singular noun. This is suggested by the definition.
'he' is the wordplay.
I cannot quite understand how this works, but
'he' could be 'rik' and 'rik' is located in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for striker that I've seen before include "player likely to score goal" , "Worker engaged in official anti-employer action" , "disaffected employee" , "A forward on a soccer team" , "Industrial activist" .)
