Karl Marx, in 1875, critiques seeing workers as only workers, diminishing them through categorization and ignoring their diversity of human beings.
Contradictorily, to be “brought under an equal point of view” is a social form we apply to better measure and account for equality.
“… unequal individuals (and they would not be different individuals if they were not unequal) are measurable only by an equal standard insofar as they are brought under an equal point of view, are taken from one definite side only – for instance, in the present case, are regarded only as workers and nothing more is seen in them, everything else being ignored.”
