I'm not sure... I get the sense that eggs of the 1800s were likely a byproduct of having chickens, or barter with someone who had chickens. Yes, some effort went into them, where now it's more likely that the effort goes into work which turns into money which turns into eggs.

But, I've made a choice: I'll pay for eggs at the market rather than have chickens, because I don't want to have to deal with chickensitters when we got on a trip. This is the sort of choice that the person you're replying to is talking about.

No. I remember eggs 50 years ago, they tasted better, as did many other foods. Extrapolating, centuries ago, eggs were like divine ambrosia.

You could replace 100% of your diet with eggs by programming half an hour each week. Most other foods are cheaper per calorie.

now they come in nice little disposable cardboard boxes, and they're available within a mile or two of your home, 365 days a year, probably about 24/7, regardless of season, or any diseases sweeping through the chicken population. it's possible you've never had to smell chicken shit in your entire life. they're sorted by size, graded by the USDA, run through certified facilities with quality control experts doing I don't even know what, but i'd wager a cookie you vote for people who pass food safety laws, so i'm assuming you approve of those QC folks.

if we round up and say a dozen eggs costs $5 right now, and then use CPI to go backwards to 1913, what we're getting would've cost $0.16 then. the first website i found says that a dozen eggs cost $0.37 in 1913. i realize there's some circularity in there with eggs being part of the CPI calculation, sorry.
