Half of inflation is economic reality having little to do with the president and half of it is corporate greed. If you think the two are equivalent I submit you haven't analyzed the situation accurately
Although your first sentence is probably half true, there were a few stimulus signed by both the previous and standing president which contributed to the issue as well. The amount of money that was printed between 2020 and 2022 did indeed help with inflation, which was signed off by both presidents.
They're not equivalent in reality (that wasn't my point, but you seem to think it is), but your argument lacks sufficient detail and presents an ambiguous enough framing to make it applicable to Biden as well.
