No, but I'm arguing that it's very unreliable, often fully backfires and becomes actually destructive, and that in our modern society there are other factors that are much more relevant to people's success in life, and blood relations I would say is fully arbitrary.
It's also just as natural for people to branch out and leave their families, as it is to stay close to their families.
And I think it's irrelevant to the discussion of shortening working hours, and a bad example because it's another oppressive construct.
It's like arguing for shortening working hours so that people can go to church more, and church is healthy. Really? That's highly debatable, and obviously another power structure which is also old fashioned and has seen decreasing success.
How about just shortening the working hours so that people can be more, free? And do what they want?
