If you were looking into that “one value” for all the wealth sold, and wanted to account for Awesome Since June 1985 37th Birthday Vintage Retro T Shirt in “real terms”, then you are still likely to be measuring the value of the wealth in terms of a given currency. The value for any amount of wealth is measured in terms of what that currency buys at a certain point in time. To translate that into something we might call the real value of that wealth we have to ascertain how much of the same currency would be required to purchase that wealth in an “anchor year”. The ratio of the amount of money needed to purchase the current amount of wealth today versus the amount of money needed to buy the same amount of wealth in the anchor year, gives us the inflation rate. For example if 110 million dollars pays for all the wealth sold this year and 100 million dollars pays for the same amount of wealth sold in the anchor year, which was 5 years ago, the inflation rate is 10% over 5 years or 2% per year average. The total “real” wealth sold would a hundred million dollars. The value of wealth sold measured in terms of what that currency would buy in the anchor year is 100 million.
