Imagine if your parents butted into your job search and career decisions, your love life, business and finances — even spiritual matters. They might mean well, but you’d be mortified.

Well, for tens of millions of millennials and Gen Zers with uncertain job prospects, high student loan balances, useless degrees and avocado-toast-eating ways, this is a daily reality and a reasonable expectation.

Marriage and kids are getting postponed, among other big life decisions. No wonder anxiety is at an all-time high, despite the growing economy.

And, in a far cry from the old American tradition of kicking a kid out of the house at 18, surprising numbers of middle class and above parents host their adult children back home well into their twenties and even thirties, hovering around and haranguing their kin about finances, work, marriage, spirituality and other life choices.

Anecdotes abound among hiring managers of helicopter parents trolling them on Twitter, calling, sending cake and otherwise butting into functions formerly reserved for adults without family interference.

The impact of helicopter parents, who’ve raised their children on a steady diet of participation trophies, “You can be anything you want to be,” tutors, grade inflation, bumper lanes and safe alternatives, has long come home to roost.

Millions of “kids” well into their twenties and beyond feel unengaged at work, incapable of meaningful friendships or romantic relationships, saving for a rainy day, paying off their student loans, holding down a job for more than 18 months — or impressing their parents with their accomplishments. Many are drifting through the gig economy while building their “portfolio careers” without a steady income, meaningful health coverage or a 401(k).
