The bourgeois factory farm is a menace but because of the usual competitive drive that showed in Dickens time leading to eg child labor and 16 hour days - but which here has no one to rebel and it’s all hidden by the separation of production and consumption. The operative principles, market and competition, are near universally praised.
This quite particular hyper capitalistic system is the origin also of the sentimentalist point of view you think opposes it by erasing distinctions and ignoring structures — it is a point of view which necessarily calls us depraved for leaving the wolves and deer in peace. It is clear that deer are perfectly conscious and suffer but also that the nature in which wolves eat them is inviolable. This involves no rationalization but is simply the truth.
