"Obama's YoY for the final three years are 2.3%, 2.7% and 1.7%"
Yes, but those were brought down by a unlucky quarters in between. If you look at quarter-by-quarter GDP growth from 2012-2020, you'll see Obama had way more quarters above 3%, 4%, even 5% than Trump ever did. Trump came into office promising 4%+ GDP growth, he never achieved it in any quarter.
Let me give you an example: Q1'2014 had a post-xmas slump of -1.4% growth. But Q2'2014, Q3'2014 had 5.2, 4.7, with Q4 hitting 1.8. So yeah, if you average that out, it's ~2.4%, but that's obscurring that there were two blistering quarters.
"Unemployment fell from 10% to 4.7% Employment rate under Trump's presidency has been also growing steadily until covid"
Yes, but the scale of the change from what Obama started with was much larger and deeper hole: a banking crisis. (If you look at IMF/WB studies of historical banking crises from the Great Depression up through Japan's lost decade, over 400 in their study, they're the worst recessions to dig out of, not V shaped at all). If you look at total number of jobs created, it was 10 million in Obama's second term. Trump ended up with -3 million, but if we're fair, and just compare Trump's best 3 years, with Obama's last 3 years, Obama had 3.0, 2.7, and 2.3 million jobs. Trump had 2.2, 2.7, 2.1, or 8 million vs 7 million.
There's no sense in which the Obama economy was "bad" compared with Trump's first 3 years. Except for the fact that they didn't rescue home owners, just the wealthy and business internets, and so a ton of people lost generational wealth, and permanently exited the job market when their only factory or sector rolled up.
Which is one more thing to say about recessions: There are some business sectors that are zombies -- dead men walking. Dying a slow death, everyone can feel it, going through the motions, and it is generally not until there is a recession that these businesses are killed, never to return, often replaced by new sectors or disruptive new tech or business models.
In a way, recessions act as garbage collection, often spurring innovation. The Bush Sr recession lead to one of the greatest economic expansions since 60s.
