In recent NYT Article
Long Road to Adulthood Is Growing Even Longer, the author makes the following point on growing up and adulthood:
People between 20 and 34 are taking longer to finish their educations, establish themselves in careers, marry, have children and become financially independent
On a positive note:
For the first time, a majority of mothers, 54 percent, have a college education, up from 41 percent in 1990.
The article ends on a stereotypical liberal note:
We have not developed and strengthened institutions to serve young adults,” Mr. Furstenberg said, “because we’re still living with the archaic idea that people enter adulthood in their late teens or early 20s.”
No: new institutions aren't needed to help young people enter adulthood. The best-suited institution has been around for quite some time: the family.
