Of course, there are some cross-over costs of eggs to other products - just as the cost of fuel doesn't totally manifest itself at the pump. Still, your point is well taken. One "outlier" price does not a cost-of-living make. And fuel cross-over is far more ubiquitous and deleterious than is egg price cross-over.
I'm almost infinitely more concerned about increases in insurance costs than I am about egg prices - which should eventually settle back down. That is something insurance prices are unlikely to do in the foreseeable future, unfortunately.
