If you have worked at a public or large company, chances are, you've probably seen first-hand negative examples of quarter-by-quarter optimization for quarterly earnings; that's far from the "global maxima" or "greatest long-term good".
Whether the downsides of less public/investor transparency, less frequent information, etc outweigh the (potential benefits) is a genuine question. There are plenty of words to describe the current SEC chair, this _isn't_ an example of moronic IMO.
Why and how would it be in the public or shareholder interest?
Im unaware if any public market where similar reductions in reporting led to significant, positive, outcomes. FTSE is the common example. They had a similar “reform” circa ‘14 and FTSE companies continue to generally under perform while the LSE continues to lose listings.
