> I don't know what the disconnect is with that chart and people's observations. The disconnect is that CPI consistently significantly underestimates inflation as experienced by real people.
Slightly overestimates. Alternatives like Truflation show it lower. You may be thinking of Shadowstats, which is run by a crank who just takes the official numbers and adds a number he made up to them. I don't know why cranks always think inflation is secretly higher. Deflation is a lot worse than inflation, so if you're a doomer, believing in deflation would be more effective.
The problem is that the error integrates over time, which IMHO is why graphs like that seem to suggest our standard of living is higher than ever... when a conversation with anyone at a local bus stop will tell you the exact opposite.
