But if you want to get into it, sure. The inflation numbers are not a fixed basket of goods. They take into account elasticity and shifts the basket to weight less expensive items more as inflation goes up.
For instance, suppose you have only two goods, bread and butter. Bread costs $5 and butter costs $10, and suppose the inflation numbers are based off 50% bread and 50% butter. Now suppose both these prices double. What happens to inflation? The naive response is inflation is 100%. But no, the BLS in its infinite wisdom realizes that if butter doubled, you'd likey consume less of it and opt for more bread! So maybe now the breakdown would be 75% bread and 25% butter, so your basket that cost you $7.5 now costs you $12.5 (0.75 * 10 + 0.25 * 20). Inflation is only 67% compared to 100%. Trillions of dollars of government spending tied to inflation (e.g. pensions, wage increases, etc) has been saved!
In some respects its true, consumption will obviously shift to the cheaper items. But on the other hand, I want a simple objective measure of what increased money supply is doing to the price of goods. I'll figure out myself how much bread and butter I should buy.
So hence, I don't exactly "trust the experts" especially when there is trillions at stake.
But they would never play games right? The BLS is above reproach. What percentage of Americans can name anyone at the BLS or the methodology? Doesn't matter. Obviously the relative importance of Cakes, cupcakes, and cookies is 0.113, shifting from 0.188 just last month. Pretty obvious objective move.
