Damn, I didn’t even realize OP’s article was sourcing a 2023 poll. Well here are the updated numbers for 2024:

63% of Americans rate their current financial situation as being “good,” including 19% of us who say it’s “very good.”

Exactly half (50%) say their personal financial situation is excellent or good

U.S. adults scored a 48.92 on our financial well-being scale

This source puts low income consumer confidence at 57.1%

68% of respondents saying the current quality of their financial life is what they expected or better

So overall the numbers haven’t changed much since 2023 on how people see their own personal finances. Your point that, despite that, they still think the economy is getting worse just reiterates what the article is saying. For some people their finances are bad and they think things are getting worse. For some people their finances are good ant they think things are getting better. But strangely, for some people their finances are good but they still think things are getting worse. Or, to put it another way, some people think they’re in good shape, but the economy is in bad shape, which is a pretty weird disconnect. And the number of people in that last category is not small.
