How, exactly?

The biggest causes of inflation were stimulus, supply-shock, and housing prices.

Stimulus started under Trump and was the correct response to COVID. Without it we would have had even worse economic suffering that we did. Inflation was the lesser-of-two-evils.

The supply shock was global, and there probably wasn't much to do about it, besides maybe some more supply-side stimulus.

Housing is just a shit-show, but people have been grinding to get more built to address the problems for years.

But stimulus was the thing that could have been changed the most, yet it kept us from having a much, much worse recession.
