I can understand that most people do not actually stay with these forecasts. The story hits NBC, you are completely outraged about this forecast made by these economists, the thing never happens, NBC has moved onto next disaster coming round the corner, next outrage.
If you work in markets, you are confronted with the relentless inability of talking head economists to just say mildly rational things. It is constant, almost every year now we have this latest economic disaster by economists in the periphery of political parties...no-one pays attention to these people, they have tenure, they make money from cashing in their political contacts not through actual correct forecasts (and yes, they always say that the thing they predicted will definitely happen next year now).
Stopped clock is eventually right. But there was literally zero information in the insane claims made in Q1. If you did not see this immediately, don't pay attention to these forecasts.
Whatever happens next is irrelevant, it won't make that prediction correct.
Could you imagine Amazon increasing their stock on hand by 30%? Maybe. Could you imagine them quadrupling their stock on hand? Seems unlikely.
Impacts should've shown up by now, most of the stockpiled goods would've been sold down.
The popular zeitgeist seems to reject the inflation numbers because of perceiving it to be higher, too.
I do agree it's probably not inventory, but the frequent changes to the policies may also be part of it too.
