The problem with measuring inflation is how it is typically calculated. I'm not a fan of either way, but the two main indicators - the Consumer Price Index and the Personal Consumption Expenditures Price Index - basically START with a list of expenses that a consumer uses in a period of time and tracks them. That information then is used to compute inflation which is a year over year index.
That by itself is why it can really be misleading, because year over year doesn't really tell the fact that 3 or 4 years ago, prices were stable and as they rise, you find yourself paying a LOT more.
I remember working with the guys who fed the data for CPI - their open disdain for how it was computed was clear - they thought it was bullchit, and I tend to agree. It's not flexible. It makes assumptions about purchasing - if bread costs too much, you consider making it or buying from the day old rack. If beef is too much, you go to chicken or pork. If restaurants charge too much, you pull back.
I imagine a better metric might be to measure how inflation affects a household, since increased cost of gas affects everything - delivery costs, grocery costs and necessary travel. Oil and gas prices affect EVERYTHING - air travel, car rental, hotels. The cost of products manufactured through or by petroleum. Electricity - and it doesn't help that on top of this, greenies are out there making it MORE expensive by insisting that more electricity is produced by more but more costly sustainable sources.
If you measure how a household meets its expenses - with dwindling dollar values and stagnant wages - you get a better idea.
BY THE WAY - have you ever - ever - noticed one thing reflected when inflation gets under control - with the exception of GAS - do prices EVER GO BACK DOWN? I don't recall ever going to a restaurant and seeing - wow - an entree is typically 30% LESS than it was a couple years ago. Restaurant prices tend to NEVER go down. I don't know how that works, since wages never keep up.
