@com2kid You're spot on. As a recent college graduate (at a non-traditional age: in my 30's) I saw a TON of exactly what you describe. Our peer group (not the Hacker News peer group, clearly, but the rest of the 20 to mid-30s group) is, by and large, listless. They simply don't have much drive or motivation. They're--as you put it so aptly--merely "existing."
I attribute this to changes in "higher" education. High school isn't about academics most places for most people; And college isn't either. High school for most people most places is about socializing and being a place for busy parents to send their kids for the work day. College is just a place to put off getting a job, and a place to party and continue socializing.
Their is a myth in college that "C's get degrees" and all you need is "a piece of paper." Students believe that as long as they have a degree in anything they'll be able to get a good job. So they select the easiest degree that matches their interests and abilities. Of course, not all degrees are equally as valuable to employers. And there's only so much demand for various specialties. But most students aren't familiar with the BLS statistics on which jobs are in demand now, how much they pay on average, what the jobs associated with various degrees entailed, and what the predicted outlook is for various professions. They just assume that a degree, any degree, is all they need and riches await. So they graduate to discover that numerous peers also pursued their easy "soft" degree in college, got average grades, and are now competing for the same jobs. The employers can't tell one applicant from another when they're all so average, so they just pick one and the rest go to work as waiters, taxi drivers, gas station attendants, etc.
In short: we're producing far more graduates in certain fields than the market requires; and far less in other fields than the market demands. And we can't really expect this to change until we start educating students in high school and college about how many jobs are available in various fields, and what they pay. We need to also work to defeat the myth that everyone "needs" a college education and that all you need is a degree, any degree, to get a good job. Some people aren't cut out for college and would be happier earning great money as an electrician, or machinist, mechanic, plumber, etc. And those who are a good fit for college would be more effective if they selected more quantitative degrees which match their interests and abilities. In other words, those who do college should not look at it as a time to put off going to work, or a time to party--they should look at it as the few precious years they have to prepare themselves as best they can to get a good job...take the hardest classes they can, expand their horizons, and distinguish themselves from their peers (do undergraduate research, do more than required, get better grades than required, diversify, etc.).
The other element is that our peer group plays the victim a lot. They don't own their own lives, happiness, or success. Granted, this is a broad statement, but many of them really place the blame for things on others. They blame someone else (the government, evil corporations, etc) for their lack of a job. They blame others for their inability to follow their dreams or carry out big aspirations (like your friend).
The truth is that for all of us, we need to take responsibility for making our lives what we want them to be. We can't blame others for not telling us how worthless a Film & TV degree is, or for not giving us a great job, or for not supporting our brilliant venture.
In short, I've blathered on at length when your post did an excellent job of succinctly saying the same thing. Thank you for your comment.
