Suppose twenty million hens die of a disease, and you order another eighty million slaughtered. That's going to lead to fewer eggs being laid, obviously, and a nonzero price increase. Now there are two questions, ① how many more eggs were laid than needed before this happened and ② if you want to look at the reason for the increase, how much of the increase is due to those 20 and how much is due to those other 80? The gentle reader has ample scope to let the answers be influenced by political goals.
