In regards to what the Baby Boomers thought of Generation X, there was wealth of articles in the early 1990s written by baby boomers puzzled at the odd habits of Generation X; many of these are even available online.

Perhaps the earliest was an article in Time Magazine in June 1990, called 'Living: Proceeding With Caution', which discussed 'twentysomethings' rather than 'Generation X', which comes from the title of a 1991 Douglas Coupland novel (and which itself may have gotten the name from Billy Idol's pre-fame 1970s punk band, Generation X).

According to Time Magazine:

They have trouble making decisions. They would rather hike in the Himalayas than climb a corporate ladder. They have few heroes, no anthems, no style to call their own. They crave entertainment, but their attention span is as short as one zap of a TV dial. They hate yuppies, hippies and druggies. They postpone marriage because they dread divorce. They sneer at Range Rovers, Rolexes and red suspenders. What they hold dear are family life, local activism, national parks, penny loafers and mountain bikes.

By 1993, when Newsweek had an editorial called 'The Whiny Generation', the nickname of 'Generation X' had become de rigueur. The Newsweek article is pretty uncompromising in its "bloody young people" attitude:

As a baby boomer, I'm fed up with the ceaseless carping of a handful of spoiled, self-indulgent, overgrown adolescents. Generation Xers may like to call themselves the "Why Me?" generation, but they should be called the "Whiny" generation. If these pusillanimous purveyors of pseudo-angst would put as much effort into getting a life as they do into writing about their horrible fate, we'd be spared the weekly diatribes that pass for reasoned argument in newspapers and magazines.

The anonymous editorial writer in Newsweek goes on to say:

That's the essence of the Generation X problem. We have a generation (or at least part of a generation) whose every need has been catered to since birth. Now, when they finally face adulthood, they expect the gift-giving to continue. I'm 28 and I'll never own a house, whines the Generation Xer. I'm 25 and I don't have a high-paying job, says another.

Are these realistic expectations? Of course not. It's the rare individual in the last 40 years who had a high-paying job and owned a home prior to his or her 30th birthday. But the Whiners want everything now. A generation raised on the principle of instant satisfaction simply can't understand the concepts of long-term planning and deferred gratification. What's their reaction when they don't get what they want? That's right--they throw a tantrum.

Bob Guccione, Jr., a baby boomer born in 1955, but also the editor of the Generation X-targeted Spin Magazine, understandably had a different perspective on Baby Boomers and Generation X in a January 1994 edition of Spin:

Generation X is a phantom, a hysterical hallucination of baby boomers, suddenly realizing they are no longer the life of the party...and like the generation before them, the boomers have turned nasty. With a speed befitting long-honed instincts of self-interest, they created the mythology of a blank generation that has inadvertently wandered onto the stage, awkward and whining, clueless what to do.

...the boomers forgot how obnoxious their parents' generation was, and that their objection to advancement was that it displaced them from the inotxicating power position. The same thing is happening today, except that the boomers built and control the machine of mass media, and so like propagandists, they manufacture images of 18-to-30-year-olds as psychologically and emotionally handicapped, like retarded children. They twist the natural tendencies and characteristics of young people into a sweeping indictment of the generation as useless.

Perhaps the most amusing baby boomer complaint about Generation X I found was an 1995 article in the LA Times by columnist Dana Parsons, lamenting that young people didn't seem interested in Woody Allen's movies:

I took in Woody Allen's new movie "Mighty Aphrodite" last weekend. I loved it, and so did the audience, applauding at the end. You know you're among friends at a new Woody film, but in eyeballing the crowd, I couldn't help but notice that no one appeared to be under 40.

Parsons goes onto interview young people, most of whom have either not heard of Allen or are not interested, and one of whom thinks she means Woody Harrelson. Parsons tries to admit that maybe Allen is for a certain crowd, but she seems to think it important that Generation X admit that this baby boomer icon is brilliant:

To be sure, Allen has never had across-the-board cinema appeal. As with all art, tastes vary. The neuroses, biting sacrilege and New York bent that dominate his films aren't for everyone, and that's fine. But the next generation must at least sample the Allen observations ("How do I know why there were Nazis?" one character groused. "I don't even know how the can opener works.").

According to one Generation X member interviewed by Parsons:

Vianne Neblett, 25, said she's basically boycotted Allen films because of his romantic involvement with his adopted stepdaughter. Besides, she said, "he doesn't market himself to our generation. It's all about midlife crises: 'I'm a hypochondriac, I'm having a heart attack, I have a tumor.' "

Despite this, Parsons is sure that Generation X would like Allen if they gave him a chance (and or, possibly, were having midlife crises like a proper baby boomer in 1995?):

I can't make twentysomething people like Woody Allen, nor would I want to. All I know for sure is that Woody Allen can't be passe. When he becomes passe, so will the human experience.

So yes, the kind of Baby Boomers who'd write columns about it in newspapers and magazines often did have a certain 'get off my lawn' attitude towards these new young scruffy upstarts that listened to Nirvana and liked Jim Carrey rather than Woody Allen.
