First of all, you have to realize that it's impossible to measure inflation and purchasing power objectively. It always depends on a highly subjective (and gameable) basket of goods. But inflation and purchasing power are a thing, so it's a bad idea to ignore them. You just have to keep in mind that all these economic time series are a lot less accurate than they seem.
