'made richer by' is the definition.
I can't judge whether this defines the answer.

'two thousand invested in innovative ideas' is the wordplay.
'two thousand' becomes 'ggrand' (I can't explain this - if you can you should believe this answer much more).
'invested in' means one lot of letters goes inside another.
'innovative' indicates an anagram.
'ideas' anagrammed gives 'aised'.
'ggrand' going within 'aised' is 'AGGRANDISED'.
