This past year it became OK to be ageist. It became acceptable to digitally flick off your elders or young’uns on social media, to respond “OK boomer” or “OK millennial,” when, in truth, the people being addressed were often far from OK.

While many people — though certainly not all — try to be more sensitive about race, orientation and heritage, ageist tropes ran rampant.

“Age-based prejudice is the last acceptable form of prejudice,” says New York University’s Michael North, who studies ageism in the workplace. “People are making age-based generalizations and stereotypes that you wouldn’t be able to get away with about race or background. Insert some sort of racial or ethnic group, or ‘OK woman,’ and it wouldn’t go over too well.”

In 2019, the baby boom was blamed for almost everything: the fate of the planet, Congress, college debt, plastic straws, the ending of “Game of Thrones.” An entire generation was perceived to be operating as a giant monolith, mind-melded in its intention to make young people miserable for the rest of their long lives. Never mind that old people were once young, struggling, loaded with debt, facing a lousy job market, expensive housing, inflation.

The sewer of mockery flowed both ways, upstream and down. It was funny, except when it wasn’t. If young folk derided "the olds" for leaving an environmental and fiscal mess, the baby boom was happy to sling verbal mud in their direction.

After “OK boomer” erupted, AARP senior vice president and editorial director Myrna Blyth said in an interview with Axios, “OK, millennials, but we’re the people that actually have the money.”

Environmental activist Greta Thunberg, 16, was anointed Time’s Person of the Year. “The Power of Youth” declares the cover. Thunberg, in her September United Nations climate summit address, squarely put responsibility on earlier generations: “You are failing us. But the young people are starting to understand your betrayal.”

Generational conflict has been around since adolescents perfected the eye roll. But children were long instructed to respect age and refrain from talking back, no matter how ludicrous their elders’ behavior. The practice held until the outsized, outspoken and oxygen-sucking baby boom reached adolescence and early adulthood.

More than half a century ago, young people sang of generational disdain (“I hope I die before I get old”) and preached it (“Don’t trust anyone over 30”) until they stopped because the treacherous enemy had become them. In 1969, “ageism” literally became a thing, coined by psychiatrist and gerontologist Robert Butler, the first director of the National Institute on Aging.

A quipping contest

What distinguishes these latest ageist salvos are their intensity and frequency. It’s an intergenerational quipping contest, fueled by the rapid, reductionist and unrestrictive nature of social media, which makes it far too easy to cast verbal stones. “Social media amplifies previously latent sentiment,” North says.

“My generation grew up having the internet as a big part of our life,” says Shannon O’Connor, 19, a student at Montclair State University in New Jersey, who was resourceful enough to transform “OK boomer” into an apparel line. “Newer generations aren’t afraid to speak up about what is upsetting them. The internet is where you dump your frustrations.”

Age groups tend to segregate on distinct platforms, creating echo chambers of consensus. Gen Z and millennials prefer Instagram, YouTube and TikTok (the latter is where “OK boomer” first gained momentum), while their parents and grandparents favor Facebook.

As with any bias, it became common to castigate an entire group for the behavior of an individual. Why target one person when you could blame millions? Consequently, the dire state of the planet was pinned on one generation, while another was chided for insolence and ignorance.

“These comments may be heartfelt, but there’s very little substance. It obscures the complexity of generational difference,” says Jay Sokolovsky, a cultural anthropologist at the University of South Florida, St. Petersburg. “We need to go beyond the simplistic. It’s a form of blaming a generation for the problems we’re having in society.”

Not everyone agrees.

“I think ‘OK boomer’ is funny. Newer generations aren’t afraid to speak up,” says Malick Mercier, 20, a self-described “next-gen storyteller” and Ithaca College sophomore. “Older people tell us we’re always on our phone. I feel like I’m on my voice, talking about things that matter to me.”

And he says that generalizations can hold true.

“If boomers had actually listened to our generation,” Mercier says, “instead of explaining everything to us, I’m not sure ‘OK boomer’ would have happened.”

Badmouthing the future

An unprecedented six generations, as defined by the Pew Research Center, coexist at one time: silent (born 1928-1945), boomers (1946-1964), Gen X (1965-1980), millennials (1981-1996), Gen Z (1997-2012), and To Be Named Later (tykes born after 2012).

For centuries, geriatrician Louise Aronson says, civilization was divided into three stages as they related to family, not society: childhood, adulthood and what she deems elderhood, the title of her latest book.

“Human instinct is to categorize people. That part isn’t new,” Aronson says. “What’s new is making it so generational.”

The moment a group is identified and named, people want to assign it characteristics, whether they’re shared or not. The names themselves are often folly. Is the silent generation, also dubbed “the greatest generation” by Tom Brokaw’s 1998 book on the topic, universally silent or singularly great?

“It’s not always clear where the names come from and who is making these definitions,” North says.

Historically, a generation spanned 20 to 30 years. Counterintuitively, at a time when people are waiting longer to have children, they’ve contracted to 15.

“Age is the only universal social category. Unlike race, gender or socioeconomic status, age has this inevitability, assuming you live long enough,” North says. “It’s this paradox, given that we’re all in this together, that I’m going to be there one day, and we’re making these comments.”

Any day now, boomers won’t be blamed for everything.

According to Pew’s analysis of census projections, this is the year that millennials are scheduled to surpass the baby boom in sheer size. By 2028, Gen X is also projected to be larger than the baby boom, so we’ll probably start blaming them.

In the meantime, perhaps the generations need to be kinder to one another.

“Maybe you shouldn’t be degrading us,” says O’Connor, who has sold more than 6,000 pieces of “OK boomer” merch since October.

“It’s a lighthearted joke,” she says. “In the end, we’re all human. We’re all the same in the end. We can’t really hold an entire generation to the behavior of a few.”

Besides, the “OK boomer” sales help pay her tuition.
