It's not really a question of blame. It's terrible for all of these people to be trapped in a lie, but the fact remains that the only way out of it is to realize the truth of the matter and change course. Life never feels sorry for you, no matter how much you've been wronged.
I don't know about you, but my career is based entirely on my university degree(s). And not because of the piece of paper, either, because of the crapload of stuff I learned at university which I never would have learned any other way.
Many of the people who proclaim that university is useless are programmers. No surprises there -- programming is one of the few marketable skills which you can actually teach yourself from a book. Aeronautical engineering? Not so much.
I don't think anyone would deny that a degree can sometimes help you attain a specific job.
The "lie" is the notion that without a degree, your job choices will be limited to burger flipper at McDonalds. With a degree, any degree at all, your dream job will fall into your lap and you'll be paid handsomely to do it. Obviously neither are true, but that is what pre-college aged students are regularly told.
If you have a love of aeronautical engineering, university is a fantastic place to study what you love. If you land a great job upon completion, even better. However, if you only have a love of money, studying aeronautical engineering is a waste of time. There are better and easier ways to make your fortune.
You misunderstand me. I'm not saying that a degree is unimportant; It is VERY important to getting a good job. Avoid a degree and you hobble yourself severely.
The lie is the belief that a degree pretty much guarantees you a job, which it doesn't. The degree is but one step along the way, but most people come out of school believing that it is the only step (followed by that magical "experience" that comes up with the rations), and so have a false sense of entitlement.
This is a lie that, though not always told directly, is nonetheless communicated to all students as they pass through the hallowed halls, as they complete difficult courses, as they don the robes and cap, as they "climb the corporate ladder". It's a false sense of security because they've only done part of what they need to do in order to be successful in life, and they don't even realize it!
So is it any wonder that uninformed and dispirited job seekers come at the world with plaintive cries of "I have a PHD in X and here I am flipping burgers!"?
In short, your CONTACTS get you the interview and a sympathetic ear, and your education, experience, references and personality do the rest. Without the contacts, you probably won't even get in the door to show off the rest.
