Trump absolutely made the economies he inherited worse because he's mostly beholden to shytty and provably wrong Republican economic orthodoxy, but calling the Obama and Biden economies great is...uhh...a tough look. The socioeconomic trends for the majority of the country have been on a downward slope for decades now due to shytty economic ideology pursued by administrations across the partisan divide. Wage stagnation, declining standard of living, hollowing out of the middle class, rising wealth inequality...these are all economic trends no President has really made serious efforts to reverse. Obama and Biden didn't do any hard work on the economy, they mostly capitulated to orthodoxy.
