Diana West, author of "The Death of the Grown-Up," traced the modern abdication of adulthood to the Baby Boomer generation. "The common compass of the past -- the urge to grow up and into long pants; to be old enough to dance at the ball (amazingly enough, to the music adults danced to); to assume one's rights and responsibilities -- completely disappeared" after World War II. A culture of behavioral restraint gave way to "anything goes" and morphed into the current generation's "whatever" attitude.
Look around: Junior's infantilism is of a piece with the refusal of celebrity mothers Dina Lohan and Tish Cyrus to act like parents -- and instead serve as best friends and tattoo parlor pals for their wayward daughters Lindsay and Miley.

Junior's penchant for pajamas is of a piece with perpetually stunted Hugh Hefner's fetish for velvet robes 24/7 and self-indulgent decadence. Junior's giant playpen is a cringe-inducing symbol of the Farmville-tethered, "funemployed" class of self-gratifiers who continue to live for today and spend like there's no tomorrow.
Adult Baby Syndrome isn't an isolated pathology. It's the new American Way. Or, I should say, the new American Wahhhhh.
