America is a place where a minority of very wealthy and educated people live among a disproportionate majority of subhuman cattle. There is an actual cutoff point I've found through numerous trials where everyone above the line practices and can fairly competently discuss concepts like logic, argumentation, and critical thinking while everyone below the line is sent into a wild rage when you even suggest that they adhere to some basic criteria of discussion if they want to be taken seriously. The latter would just prefer to burp, fart, and stomp their feet while emotionally reacting to whatever they can violently react to in the moment.
That is where statements like that come from. The reality is it is much cheaper overall to eat healthy food in the U.S. than it is to eat unhealthy food, but the vast majority of Americans are too stupid to even perceive any costs beyond the primary costs. When you suggest they might be accumulating costs through future healthcare complications, diminished quality of life, and so on they flip out. They actually flip out because a trait of these creatures is that if you make them aware of the costs, they treat you like you're a magical being that has personally introduced the costs to them by making them aware of it.
Americans of this type are superficially human, but if you dig into it a bit, they actually aren't that much more advanced than chimpanzees. Over enough time, you would absolutely get speciation.
