I realize that a lot of the questions and statements are meant about the "average public", but I thought it worth mentioning that there *are* people who will pay a rather large percent of their income on eggs and meat which are more expensive, due to being raised in a way that they are confortable with. Still others simply choose to eat it less often, preferring other sources of protein, which they can more easily afford.
Likewise people not buying baked goods, going to restaurants, or fast food places.
It may surprise some to know that very common looking people (vs. the image of outerfringe, which it brings to mind for some.) sometimes choose to not participate in what they don't believe in. If those individuals want bread, they bake it, (made a lot easier these days with bread machines for some.) and do the same with cakes, and other treats, and do not choose to eat fast food.
Restaurants aren't that difficult. Some do not eat out. Others choose to order humanely raised animals/eggs, which are selling points for some restaurants, and still others order vegan choices, or fish.
We shouldn't assume that all people are chained to buying what they do not want. Some have already found ways to remove themselves from the loop, and many more have taken steps to change how much they need to participate. Like, oh, close to 10,000 people on this site...at least where eggs, and sometimes chicken meat, are concerned.
And the more each person learns, the more they tend to remove themselves from conventional meat and eggs. I've heard quite a few people on this site state that they were not aware of the full scope of the problem, and were disgusted enough to stop buying items they had been using up until this point.
Each of those people will also spend time educating others that they know.
