Perhaps you need to learn what inflation is. I do agree that the numbers presented by the government are lies, though.

I remember vaguely that the stats on https://www.shadowstats.com/alternate_data/inflation-charts have also been shown to be false, but I believe them to be more accurate than the numbers of the government.

The greatest price increase for a food item I regularly buy is 50%. The problem is that the government has an interest in lying about these numbers, because they are linked to salaries paid to teachers, etc.
