I'm not asking for excellent decision making skills. I'm not even asking great, or even good decision making skills, for that matter. I'm just asking for a young adult to not approach an investment in education in the worst way possible.
A part of you has to be kidding when you ask "who is that smart," or "who is that aware," or at least I hope so. If you are 17 and cannot understand that some jobs are in higher demand than others, you have lived a very disconnected life (generally symptomatic of being a well-to-do suburbanite). If you are 17 and do not realize that this world will constantly need huge amounts of engineers, HVAC technicians, programmers, diesel mechanics, and the like for the foreseeable future, you have spent almost 20 years somehow ignoring the wonders of the modern world around you.
I had pretty much settled on working in either software development or network engineering by the time I was 13. The IBEW would be my next stop if that didn't pan out, but I never let it come close to that. I know multiple people that began developing a passion for their field around the same age as I did. I know many more people (some from unforgiving upbringings) that graduated high school, realized that they needed to make a move fast, and picked a growing field that they knew there was money in. It isn't hard, but you have to accept that you will be rewarded for committing to something in-demand quickly and decisively, even if you would rather be a rock star.
You're taking my mention of suburban-liberalism and running somewhere completely different with it. My point wasn't that college is some "feminist snowflake" plot to dupe the unsuspecting young adults of the US. What I'm trying to say is that it takes a special sort of lifestyle to make blanket claims about how any and all education will lead you to success. Tell an impoverished resident of an inner city how much you've spent on a theater degree and they will ask why you didn't spend it on immediate necessities. Tell a rural resident how much you spent on your theater degree and they will ask why you didn't enlist, become a lineman, a millwright, or a nurse. Only somebody who hasn't experienced the urban jungle or the desolation of the agriculture and manufacturing industries can sincerely act like you can get any old college degree and have it be worth your time and money. It requires you to be progressive enough to at least superficially care, but naive and disconnected enough to not understand the reality.
I don't look at students wanting a better life and working toward it with ire and derision. I am fairly irked by grown adults wanting a better life, being mentally mature enough to understand what that takes, doing something else, and wondering how this all could have possibly happened. Our "what now" is basically to tell these students to cut their losses and go through the whole process again, this time in a field that will net them decent work, while their classmates have a six year jump on them. This is a future we can avoid if we stop acting like every degree will lead to viable work.
