It’s based on the Consumer Price Index which uses thousands of items. And it changes based on consumer behavior. If for example the price of ground beef goes way up and people buy substitutes like ground pork or God help us - Spam - then it adjusts to what people are actually buying.He is using the same method for inflation rate calculations as the VA uses for disability ratings.
It sucks because all of us would prefer NOT to buy alternatives, but it would be just as inaccurate to measure stuff people AREN’T buying.
Maybe there needs to be a metric for measuring inflation based on what we used to buy, what we’d choose to buy if the price didn’t go nuts.
