I want to know the answer to the following question:
What did the Greeks offer to the Ottoman Empire that was a superb benefit ?
All the background I'm provided with is that "It was the wealth of the extensive merchant class that provided the material basis for the intellectual revival that was the prominent feature of Greek life in the half century and more leading to the outbreak of the Greek War of Independence in 1821.". Is that enough to answer the question?
Answer: no
