I dislike the condescending attitude of the author towards the young adults (referred to in the article as "children") attending college. The author claims that leaving home to live at college poses a "serious psychological risk". Are we talking about 18-year-olds or 5-year-olds? Are we afraid that these more-or-less fully fledged citizens, whom we allow to drive, smoke, enlist, vote, marry, and have children, are going to end up crying for their mommies and daddies because they left home too early? Ridiculous.
Where these "psychological risks" exist, it's probably more a symptom of failing to ween teenagers from parental dependence and teach personal responsibility than it is a symptom of college life.
To quote a younger friend of mine, who started college this year after bumming around Europe for a while: "After spending a few months 'in the wild', living in this relatively very supervised college environment seems absolutely mundane."
