In the 'normal world' we would probably use the word 'people'.
That's just the point, "Ones" is used to distance the speaker/listeners from the humanity of the persons being discussed. No "he", no "she", no "they"; only an unthinking, unfeeling, less than human "something" that the God-chosen dubbies are forced to deal with...so let it be at arm's length and best dealt with as an object.
Google the phrase "one is glad to be of service" or watch the movie "Bicentennial Man" for a deeper understanding.
