Much confusion arises from discussing inflation and CPI in the same breath.

Inflation is a process. The rate of inflation is the rate of accretion of new cash (notes and coins) into circulation plus accretion of new consumer credit (30 day balances).

Inflation supports transaction. The more inflation, the more transaction that you can have. When the amount of goods stays fixed and transaction rate rises, you suffer a rise in prices.

CPI is a meaningless measure that compares now the Check-Out Price of a fictitious shopping cart to the price at some moment during a prior year. Yet, the goods within these shopping carts change through time as well as the want of men to own them.

Any good consists of factors -- matter shaped uniquely through expended energy, time, skill and wit. Through time, as a good gets changed, the amount of factors get changed. At any near-instant moment, each factor has a known price, which changes due to supply and want of the factor.

The Buying Power of a unit of currency -- a Fedback Dollar (US dollar) -- is variable due to accretive effects of dollars added into circulation. All future transaction requires settlement (instant via cash, within 30 day billing). The more notes and coins circulating 30 days from now, the lower the Buying Power of a Fedback Dollar at that time.

To get meaning from prices, you must look at what is meaningful -- how much Work Time does it take for a man to buy a Kilowatt of Electrical Power, a Calorie of Steak Protein, a BTU of heated or cooled air, a Board-Foot of lumber, a Mile Travelled (tricky one), a Minute of Talk Time, an ATM transaction fee, a Ounce of Alcohol from barley, hops, yeast.

Since Fedback Dollars and other Currencies by Fiat suffer from varying Buying Power due to accretive effect of inflation, how does a man define a Unit of Stored Work Time?

Some men gain more Units of Stored Work Time faster than other men and at lower calorie use -- engineers vs laborers.
