Consider the possibility that, first and given the political importance they have in the present day, the official numbers that the Economists are using are less than honest.

Also, I know that some countries don’t include Housing Inflation - which is huge* - in their Official Inflation. Is that also the case in the US?

Last but not least, there is the whole difference between what is usually reported to us by Politicians, Economists and the Press, which is either country totals (which grow up merelly by the population growing) or the mean average (i.e. adding all values and dividing by the total number of points) which suffers from the “if a man has 10 chickens and 9 others have none, each has in average 1 chicken even though most have none” problem, and the mode (the value around which most cases are found) which is far more representative of most people’s experiences: if for example the wealth increases from higher productivity are going entirelly to a few people who just get ever more filthy rich whilst the many have either stagnated or, worse, are getting a bit poorer due to inflation eating up the true value of their pay, the grand total will be growing, as will the average (if the population numbers are steady) but the mode will have stagnated or even be falling, matching the experience of most people - people get to hear about country GDP growing and even GPD-per-capita growing all the while the vast majority see not growth at all, maybe even a falling of their purchasing power (the latter for sure for any who don’t already own their house).
