That is an unfair comparison. Eggs are subsidized by the USDA in the US which allows overproduction and economies of scale effects (reduction of purchase price)

That is an unfair comparison. Eggs are subsidized by the USDA in the US which allows overproduction and economies of scale effects (reduction of purchase price), but increases environmental harm (industrial farming). You are paying the price elsewhere however due to environmental effects, antibiotic resistance, and zoonotic diseases (e.g. bird flu).
