Tanking

You know the news. Here's some of the latest.
Had lunch with a clergy friend today who asked a pointed question: Where exactly does the money go that you lost in the market? (By "you," he meant the understood plural, because if I were serious about making money, I probably wouldn't be sitting in this chair.)
My friend said he was seated next to an economist on a flight to California recently; and he asked the guy that same question and he really couldn't answer.
Say you have a hundred dollars. You give it to someone to invest. But then the money's all gone (not hypothetical, as you know.) So. Where does it go, exactly?
My new theory is, we'll all be living in caves again and baking bread by sunlight. Maybe we can all go live with Eustace Conway. (See below.)
