The former administration denied the pandemic was serious, told people to go about their business as usual, denied masks should be worn, peddled dangerous misinformation about the pandemic constantly, and never seriously promoted vaccine use (we didn't find out he even received the vaccine until after he left office). The former administration also barely had a vaccination strategy. It's no wonder the pandemic exploded in the United States, which comes with the economic consequences one would reasonably expect.
I've posted numerous times in the election thread a thorough, but not full, list of how the former administration failed in its response to the pandemic. I refer you to it, since I know you've already seen it.
I'm not sure how anyone can reasonably jump to the conclusion that I'm claiming there was no meaningful job growth under Obama. His administration took us from the worst economic downturn since the Great Depression to a booming economy.
The problem for the former administration is that the rate of job growth stayed where it was after Obama left office. In fact, if you want to get picky, Obama's last three years of job growth (2014-2016, well after the Recession) were all better than the former administration's best year. The only meaningful effect the former administration had on the economy was the economic downturn that was the result of the pandemic and the administration's mishandling of the pandemic.
