Target would absolutely love to charge $1000 for a carton of eggs, and would if they could, but they can't. There has always been some ceiling price past which most consumers will simply walk away and go somewhere else. What exactly that number is depends firstly on the actual cost of getting the item in the first place, since no store will sell an item at a loss (unless they expect that to drive greater returns elsewhere), but then on how much money people actually have available to spend, and that very much is influenced by how much money the Fed is printing, among plenty of other things.
My point here isn't that corporate greed isn't a factor, but it's not a new factor. It's not like corporations were feeling generous in 2019 and then got in a greedy mood in 2021. They always have and always will charge as much as people are willing to pay, so any changes to what they're charging should be examined by looking at what other factors might be at play. In this case, they've probably realized that they've gotten past the point of driving too many customers away.
Obviously corporate PR will never come out and say "We're being greedy because fuck you, but we got a little too greedy so please come back", but that is and always has been the dynamic.
