Because parents and schools in the developed world have stopped raising kids and have instead opted for 18+ years of babysitting. Part of the problem is that we don't even know what we're about anymore, so we don't know what lessons and principles to pass on to our children. It's a wonder that the problem isn't far worse than it is already.
One of the major things I see though in the article is the way in which modern corporate capitalism isolates individuals and tries to place career above family.
Having lived in some other countries, I disagree. This corresponds with corporate domination of the economy. Where small businesses dominate, family becomes more important. The reason is that family becomes the primary source of small business capital.
(The family also becomes the source of one's "career" as well. It isn't that women don't participate in family businesses. They do, extensively. It's that family and work time are no longer separated by a wall.)
