Why politicians and banks are changing the definition of "inflation"

Economics is a quite complicated and nuanced subject, and the concept of "inflation" is likewise, but the simplest explanation of what it means is that the value of money (ie. its purchasing power) decreases when the total amount of money in circulation increases (ie. when more money is printed and put into circulation than previously), which in turn causes a natural raise in prices (which is caused by supply-and-demand: When people have more money to spend, the price of commodities will start raising accordingly.)

As most dictionary definitions (still) put it, "inflation" in economics is (emphasis mine):

a persistent, substantial rise in the general level of prices related to an increase in the volume of money and resulting in the loss of value of currency (opposed to deflation).

In other words: The more money is printed (compared to the past), the less valuable the money becomes.

What this means is that the government and the central banks in charge of printing money and putting it into circulation can control how the free market behaves: Print more money than before, and prices will start naturally raising to follow suit.

In the last few years, however, the people in charge of that are trying to change this definition of "inflation". How are they trying to change it? By removing that part that I emphasized above. In other words, remove the "increase in the volume of money" part of the definition, and just leave the "rise in the general level or prices".

The reason why they want to remove that part of the definition is quite clear: To deflect blame away from themselves. Suddenly it's not their doing that's causing your money to lose its value. They are completely innocent. It's those greedy manufacturers and shopkeepers who want more money for their products and want to suck you dry. It's those greedy workers who are demanding salary raises to compensate. They are the ones guilty of inflation and decreasing the value of your money! They are the ones to blame! It's not the government and the banks printing more money than has ever been printed during the history of humanity, it's the greedy shopkeepers! They are the ones to blame!

The attempt at subterfuge in the form of wordplay in order to try to deflect blame from themselves is so transparent as to be completely ridiculous.
