Veganism can take a lot of effort if you are poor just in terms of what is available in a lot of places in the US. Cheap processed foods with animal based ingredients are often more available than a good selection of vegetables and non-meat proteins, and easier if you do not have a lot of time to cook.
Effort is irrelevant in determining morality...
Often it is, but I was responding to the posters here (esp those on the other side of the pond where the economics of this are likely quite different) who were confused by the claim that poverty makes an impact on this.
I'm not sure I've ever met a single meat-eater who consistently buys from Certified Human sources...or even regularly does.
Human meat sources are typically left uncertified.
(good post tho)
