Mine is that it's a very simplistic analysis, and should just be ignored. Using the CPI which has been gamed, and changed so many times is the first large flaw

Mine is that it's a very simplistic analysis, and should just be ignored. Using the CPI which has been gamed, and changed so many times is the first large flaw. You know how that bag of potato chips stays the same price, but the weight of what you're paying for keeps on lowering? Yeah, that's not inflation per the CPI because it only tracks actual price increases. What about how they switched to substitutes? The second, is that it completely ignores global trade, and currency valuations. There's a lot of complex interactions, lag times, and host of other factors that affect pricing at the micro level, and that won't affect all products in the same way.
