> No, some interventions leave things worse off than it would have been without. When it comes to the public's money, and truly stupendous amounts of it at 25% of GDP, the bar has to be a lot higher than "eh, probably better". I suppose it's a job for economists and historians in the future to study this, but one wonders if there is some relationship between the amount of Covid stimulus response and the recent inflation, and how persistent it would be in the years to come.

Yes, some interventions leave things worse off than without. But with sudden massive unemployment and low savings, why do you think the default hypothesis is "nothing would be better"? You can have both "persistent lingering inflation for several years" AND "still better than the alternative."
