Used to, as of when? The good old days of the 1990s? I think it goes back a lot further than that. For a much more thorough look at how our modern financial systems produce what naive thinkers would consider to be bizarre results, I highly recommend Mariana Mazzucato's "The Value of Everything." It's a challenging read, but it goes into the details of how economic and political thought has shifted over the centuries regarding the concept of wealth and value creation, and how the game really works.
