LOL, ok there's a few factors at play here.
1: most Americans don't even understand what the economy IS. when you ask them about the economy, they're going to answer w/r/t their personal finances. which, for most Americans, suck.
2: stop looking at the stock market. the stock market has zero to do with how people are faring economically. most Americans don't even own stock.
because Republicans don't argue in good faith. they aren't honest about anything. Republicans are spamming social media with shit like "WE WERE BETTER OFF UNDER TRUMP" purely because the guy they liked was in charge. purely because he pissed off people they don't like. they would gladly be rounded up and executed by Trump and they would claim they're better off for it purely because it would upset people they don't like.
I think Republicans are honest in a backwards way. Their accusations are confessions.
US: capitalism sucks
NYT: you silly zoomers with your tick-tocks, the economy is doing great! your negative memes are fucking up the vibe!
