Produce, when you up the wages of (4,4,2)

'produce' is the definition.
(synonyms)

'when you up the wages of' is the wordplay.
I cannot really see how this works, but
'when' could be 'e' (I've seen this in other clues) and 'e' is present in the answer.
'up' could be 'is' (I've seen this in other clues) and 'is' is found in the answer.
'the' could be 't' (the is pronounced as a 't' sound in some dialects) and 't' is found within the answer.
'of' could be 'o' and 'o' is present in the answer.
This explanation may well be incorrect...
