You are misreading the first chart; it doesn't show a decline in prices it shows a decline in the rate of inflation.
As spokey said those charts don't reflect the reality people are facing. It's common knowledge that they fudge the inflation numbers and consistently understate inflation. The 2nd to last chart doesn't reflect reality at all. If I had to work an extra ~30 minutes per week to cover groceries from 2021-2023, I wouldn't have even noticed it nor would most Americans. I'm paying ~twice as much for groceries post Covid; that's roughly 25% per year post lock down.
Maybe I'm not grasping what you are getting at, but the first chart is the CPI, which is the PRICES of that "market basket" of goods. The very definition of CPI is "
a measure of the average change over time in the prices paid by consumers for a representative basket of consumer goods and services"
If the CPI chart isn't about "
change over time in the prices paid", then what does it represent?
And if the prices represented by the chart are fudged for Biden, then we must assume they are also fudged for Trump and every president before him. Any discussion or comparison of prices becomes moot, because nobody knows the real data, and has no basis of comparison.
Does the chart not reflect reality, or not reflect your personal reality?
Do you call bullshit on the average price of gas in the US being $3.03/gal if you are in California and paying $4.65?
Average is a misnomer...only a small percentage see the "average" in any kind of poll, graph, whatever...
But a large percentage are close to it, especially with a dataset as big as the US. That's how averages work and why they can use them to make predictions about data sets that include hundreds of millions of examples.
The average US salary in 2022 was $63,795. The median was $60,070.
How can that be, when Elon makes $350,000 per hour, but Ted makes $7.25/hour?
MATH.
