It is, Robert J. Samuelson argued in a recent column, a bad time to be a 20-something.

I could have told you that.

It’s always a bad time to be a 20-something.

Back in medieval times, 20-somethings had it hard because everyone was saying, “Hey, you are in the throes of your ripe middle age.”

Since then, each generation has faced its own challenges.

The expectations are high. The world is your oyster, they say.  The sky is the limit. All life lies stretched out before you, like a kitten demanding a belly-rub.

Except that it’s not. Youth once ruled the world. People telephoned us 18-29 year-olds, read us elaborate surveys and listened, rapt, to our preferences.

Now youth still rules the world, but younger youth. Tweens run things. Tavi Gevinson runs a magazine. Before Psy mercifully overtook him, Justin Bieber had the most-watched YouTube video of all time. Justin Bieber, of all things! Get off my lawn!
