Not having easy access to quality meat and dairy because of the disgraceful state of American agriculture is directly related to standard of living. (not saying this is a uniquely American problem, but that's what we're talking about here)
If you're talking about the sheer gluttony of many Americans, I agree. But that is mostly a product of groups that eschew personal responsibility/attempt to justify their disgusting habits through "acceptance."
I'm talking about the poor quality of meat and dairy in the US.
Do you mean the way its produced? Like with all the preservatives and chemicals put in them? Iirc I read an article that processed meat has been linked to a higher risk of Colon Cancer.
