I just realized, why consumer price index cannot possibly work as a measurement of inflation.
By definition, it is based on price of goods, that an average person buys, and weighted by the ammount.
Well, if chocolate goes to doubble price in an year, so I decide to stop buying it, the change in it's price does not even affect the inflation numbers, since it is now weighted at 0. Same goes for housing and energy. If I cannot possibly ever afford a house, guess what? The weight variable will go to shit too.

So, I agree completely. It's a perfect tool to hide inflation, instead of actually calculating it.
