This article talks about "justifying" profits. I think that's backwards. Profits justify businesses - making a profit is why people make cars, beers, whatever. Companies don't have to justify their profits if their consumers are willing to buy them.
The article mentions the spike in profits for Cal-Maine foods. That's well trod ground for this discussion. The author also, to his credit, mentions that avian flu devastated competitors flocks (50+ million birds killed) but didn't touch Cal-Maine. The other part of the puzzle is that Cal-Maine had a bad fiscal year the year before so year over year profits look like a huge spike.
I don't really see how you can discuss inflation without recognizing that the creation of lots of new dollars is going to play a big role. If we start regulating profits we will disrupt markets, not make them more productive.
