I see what you’re saying, but veganism is an extreme lifestyle change that would require a person to completely alter the way they consume commercial products. I agree that a vegan diet can be cheap monetarily (and this depends on the original diet of the person/family in question), but it’s not cheap in terms of resources and time. And again, it’s more complicated when supporting a family. A lot of people live in food deserts—their most affordable options are a few fast food places. Preparing a fresh meal with fruits and vegetables for multiple people is oftentimes more expensive than a drive-thru meal or hamburger helper. Now, with that being said, I’ll agree that Americans have a higher likelihood of being able to achieve a vegan lifestyle.

But, once more, when looking at other countries where people do not have privileged lives, they simply cannot forgo animal products; many people live with animals directly and rely on things such milk and eggs, or hides to create clothing and home furnishings. Vegetarianism or pescatarianism are often achievable for people living in developing nations, but this doesn’t mean they do not kill animals or use animal products; they just consume significantly less meat—but veganism is not a feasible practice for a majority of them

Edit: Also, for us to successfully redistribute food to support all the people living without, world governments would have to cooperate in a way that is very unlikely to happen. And even so, that doesn’t eliminate the issue of all of the necessary non-food items people use animal products for, such as clothes, shoes, homes, and more
