'reducing social differences' is the definition.
I don't know anything about this answer so I cannot judge whether this works.

'education' is the wordplay.
I cannot quite see how this works, but
'education' could be 'class' (class is a kind of education) and 'class' is present in the answer.
This may be the basis of the clue (or it may be nonsense).
