Because for most Americans financial well-being is how they interpret the concept of being "better off" in which case, they're right. They had more money and spending power 4 years ago than they do now. You seem fine ignoring the average voters opinion because it doesn't match the DATA yet when the DATA backs up something you dislike you become a CNN anchor. The stimulus checks and unemployment benefits did a lot for people. Just because they couldn't eat inside a restaurant doesn't mean they weren't doing better financially.
Not ignoring the opinion I said the opinion is wrong. Opinions can be objectively be wrong. 70 degrees F can be warm to a voter in Minnesota yet cold to a voter in Florida. The modern news landscape has been failing the population because they will run a story on why it doesn’t actually feel like 70 degrees instead of just reporting what the damn temperature it is. And right now it is a coin flip if US democracy survives this.
