A couple things might have changed. First, the shared experience of the pandemic may have increased the average level of empathy - outside of some nutjobs. If you're doing okay but you care about the people around you struggling you won't think the economy is doing well.
Second, income inequality is now higher than at any time in history. Many Americans would probably put "fairness" as part of the criteria for how they judge the economy. While it's nice that your wages are keeping up with inflation, your boss's boss's boss's boss's boss got a seven-figure bonus on top of his eight-figure salary and nine-figure-plus net worth.
And while this will definitely raise the median and mean incomes nationally, people won't feel like things are improving, leading to data that makes economists shrug.
Then again, until recently economists had to create an entirely new species of hominid to explain their theories so I don't trust them to have a good idea of how normal people think.
