Reply #16: I disagree with the assumptions.

Also from the article:

National surveys reveal that an overwhelming majority of Americans, including younger adults, agree that between 20 and 22, people should be finished with school, working and living on their own. But in practice many people in their 20s and early 30s have not yet reached these traditional milestones.

Should be finished? Who set the ages at between 20 and 22? Why is this age range better than any others? What intervening variables within society are involved in such outcomes now as to compared to say, 20, 50, 80 years ago? More education than parents? Lack of job opportunities that pay a living wage? More mobile society with fewer interpersonal connections in places where they work as opposed to where they grew up and where close ties were first formed? Marriage losing its status as a desirable end-point in one's life?

At best this so-called "study" raises interesting questions, but I don't think it answers very many. But still, I'll K&R.
