AFAIK, humans cannot be compared as equal by any measure. The law does not consider equality but reciprocity (“exchange of consideration”). We use the term ‘equal under the law’ as a proxy for reciprocity, simply because in the past, different classes could seek privileges of rank (largely differences in restitution). We are in fact always and everywhere unequal, which is why reciprocity solves the problem of our inequality. Better said we are not considered whatsoever by the law, only our property. We have no part in it. As such the law does not treat us equally, it ignores us entirely and considers only the property transferred.
