The inflation was inevitable. Could his spending have exacerbated it? Definitely possible, but this was going to happen.
We had poured (because we pretty much had to) about $11 TRILLION total into markets in response to the Meltdown, and we all knew that it was going to cause inflation down the road. We kept interest rates artificially low for the same reason. Then COVID hit and global supply chains collapsed when global demand exploded coming out of the lockdowns. Then the goddamn Fed was about a year late in addressing the inflation adequately. By that time, the inflation had begun to feed on itself and we were screwed.
It was going to happen. The Fed has done a very good job since then, VERY good, which mitigates how pissed off I am that they waited so damn long.
Inflation could easily remain below 3.0% for 2024, and we could also have very solid growth with it. No one can predict it, though.
