I just want to respond to the discussion about the government reported inflation rate. It's based on a government calculated CPI (Consumer Price Index), and the products and services that are included in the CPI change every month based on whatever will make the numbers look good. For example, gasoline and health care costs are NOT included, in addition to other "volatile" products that get swapped in and out of the CPI on a monthly basis.
Think about it. The government stands to benefit the most from positive economic figures, and the government controls how those figures are calculated. By manipulating what gets included in the CPI the government can under-report inflation, and over-report production. Here's an exellent article that explains how this is done. Check out Table 2, in particular:

The government also uses a technique called "hedonics" to factor in improved performance in automobiles and computers. They also use "substitution" to try to predict what a consumer might do when faced with higher prices. The bottom line is, these adjustments just allow them to manipulate the true economic statistics, and are based on nothing more than some statistician's whim.
Here are two articles that discuss hedonics and substition as they relate to the government's bogus inflation statistics.

Lastly, check this out, straight from the BLS (Bureau of Labor Statistics). Here's an example of how they use "substition". In effect, they can simply substitute out the goods that show large price increases until the final numbers look they way the government wants them to.
Substitution can take several forms corresponding to the types of item- and outlet-specific prices used to construct the basic indexes. . . . Thus, in response to an increase in the price charged by a store for a certain brand of ice cream, a consumer could respond by:
Redistributing purchases:
To another brand of ice cream whose price had not risen.
To a larger package of ice cream with a smaller price per ounce.
To ice cream at a different store where ice cream is on sale.
To a brand of frozen yogurt.
The consumer also could respond by postponing the ice cream purchase until a later date.
Finally, the consumer could substitute from the ice cream brand to a specific alternative dessert item, such as cupcakes or apples, which is another CPI category.
This latter form of substitution, although across CPI categories, would still have the effect of reducing the quantity consumed of the higher-priced ice cream brand relative to the quantities of other items within the ice cream stratum. . . . In the same way, the use of the geometric mean formula within categories does not address the issue of whether consumers can, or do, respond to a general increase in the price of ice cream products by, for example, forgoing dessert.
-- Quotes are from a BLS document, "Incorporating a geometric mean formula into the CPI." The emphasis is mine.
