In my setting the primary objective of the top wizards isn't gold or glory. They're not all that interested in devising new spells or enchantments for their own sake or for their practicality.

What they want above all else is to discover the underlying truths of magic and so they do basic magical research. As a result they learn really impractical spells and enchantments. So when you find their treasures don't expect these to be much use for a muggle.
