Nobody was complaining about low egg prices when Cal-Maine was reporting losses and meager profit margins in 2017 and 2019 to 2021.

But that is beside the point that there is no set nominal “appropriate” profit margin for a given business.

That does not mean that businesses with high profit margins are not colluding, or corrupt, or acting in ways that should be illegal.

But it also means you cannot simply conclude from a few quarters of higher profit margins that a business is behaving unethically.
