You need a citation that some guy once said that the amount of wealth in the world is not fixed? What would the world look like if it weren't true? There's no reasonable or useful definition of wealth for which the world of today has exactly as much wealth as the world of 10,000 years ago. (Or 1,000, or 100. 10, well, that can be successfully argued either way. It's not been a great 10 year run.)

I believe he's looking for a reference that Locke was a proponent of the idea, not that the idea is true. Similar to how you might ask for a reference if somebody suggested Shakespeare as the originator of the Theory of Relativity — it's not that you disagree with relativity itself, just the history given.
