People were actively deceived along the way. Do you remember that intially Yellen (and Powell together) called the inflation "not broad enough to be considered inflation", then called it "transitory" and justified printing so much money all the way into 7% inflation. At 3% PCE, Powell said everybody to relax, that nobody should doubt they will use every tool they have to fight inflation. Bostic at 2% PCE said he is not worried, he welcomes higher inflation, approaching 4% inflation would be cause of concern and would require action. Action that never came. They just lied and misinformed the people for years. People listened to this, it was all over the media. It's wrong to suggest people didn't listen.
Do you remember after 5 years of review they came up with symmetric inflation target of 2% and they instantly abandoned it because that would require lower inflation for decades to come. And nobody in media questioned it, they said people "misunderstood the target".
They don't want to educate people about the economy, they want people as stupid as possible.
