This is why rightoids don’t care what leftists have to say about the economy fam. It doesn’t matter to them if your overall point is correct when you go around redefining words to fit the agenda just because you don’t know the actual terms.
You could have tossed out terms like purchasing power, cost of living, or even just slapped “effective” in front of inflation to sound like you remember your high school economics but instead you decided to call a deflationary pressure double inflation.
