Do you know the John Candy movie "Only the Lonely"? Not every child leaves home. Some become so emotionally entangled with a parent or parents that they never leave home. That relationship becomes the principle relationship of their life.
Not that long ago this would have been normal. Again, using an American reference, I would ask if you are familiar with the show "The Waltons". A show depicting rural American family life in the 20's/30's. A life that was characterized by an extended family living in one house.
The idea that you could find a job and become completely independent is very new socially. Particularly for women. It may not last if times get hard.
That being said, I agree with you that raising your kids to be dependent is poor parenting. Anything worth having in their life they are going to have to work for. Teaching them the value and power of work in building the life they want, would seem to me to be a critical lesson.
