I believe the answer is:

water wheel

I'm a little stuck... Click here to teach me more about this clue!

'a long-established driver of industry' is the definition.
I can't tell whether this defines the answer.

'were wealth to be redistributed' is the wordplay.
'to be redistributed' indicates an anagram (I've seen this in other clues).
'were'+'wealth'='werewealth'
'werewealth' anagrammed gives 'WATER-WHEEL'.

Can you help me to learn more?

(Another definition for water wheel that I've seen is " turbine".)

I've seen this clue in The Independent.
