Reality is, these institutions have failed for a long time. It gave me a chuckle when I read the line "maximum unemployment and price stability". The official fed numbers for those are way off, you tell Americans spending >50% on their groceries compared to 2-3yrs ago that the inflation is 4%. Or unemployment rates for that matter. All the numbers are garbage, nothing means anything anymore.
If congress and Fed had a spine to enforce meritocracy, Jerome and all the "transitory" shenanigans would have been out long ago. And so there you have it. Officials with 10 years terms with zero accountability for their decisions with revolving doors to follow having big bucks consulting gigs for big banks awaiting moment they retire will say and do anything to preserve the self-serving institutions. Not its mandate. And cherry on top, if they are lucky to play out well, on their way out will get the glory of "serving the people and protecting the institutions".
