Inflation/deflation indexes are massively skewed if you don't incorporate the right things into it. How sure are you that these indexes are factually correct?
Keynesian economists think that Japan's real estate implosion was deflation.
Back in reality, Japan hasn't suffered any real deflation in 25 years. Which is why their prices are among the highest for pretty much everything.
The deflation argument is a fraud cover for the failed Keynesian experiment. It's meant to give them the ability to endlessly print to debase the debt that the failed experiment took on. That's why the US Fed pretends to worry non-stop about deflation, while they massively expand the monetary base and hold rates at zero; it's a lie to provide cover for the massive inflation programs.
