Though, maybe not. I could totally see someone being really interested in the structures of everyday life of medieval peasantry. Seems worthless, but you could totally parlay that into a profitable business doing furniture making or even green/natural/traditional housing.
The kind of money that is available in finance to someone with an advanced degree in math or physics is nothing short of astounding, with CS a distant second. Of course, there are all kinds of ethical compromises one must make for that.
so this supply-demand thingy - its just something that happens to accurately describe the current state of the world, or more particularly the usa, especially in a bubble where it is infinitely more preferable to drop out of college and pursue ruby on rails than stick it out for a lousy diploma with your name on it. but if an athlete wanting to compete in the olympics mistakenly walked into a circus and started jumping through hoops, the crowd would throw coin at him. he can then collect that coin & settle down, get married, raise a family, get a drivers license, buy an automobile, pay municipal state and federal taxes & so on. but that just means he's become a clown, not an athlete. it is unfortunate that athletics is non sexy and training to be one involves grueling practice for years and years in isolation with no attention, no fame, no coin. but to dodge that work and passion because of what society chooses to value at a particular point in time is quite defeatist. none of what we do in cs today would have been considered useful in the 20s and 30s. church and turing would have clearly been better off working in the railroads or digging an oil well. yet they did what they did, and here we are... so, respect. you never know what the future holds for medieval history or english literature. i spent 3 semesters as a film major before i dropped out, and i must say it was a royal blast. repeatedly watching blondes strip and run towards the beach in their red bikinis while their breasts bobbed up and down, and the professor of film studies pausing the remote at the critical instant when a tad bit of cleavage was visible and saying "hey, this is why baywatch was a hit" and all of us students scribbling down "must place camera on sand level and tile up to show cleavage in beach shots" - i mean, nothing beats that. no amount of fancy research in STEM will match the pure adrenaline that passes for film studies. so there's a reason people in their youth pursue these non-lucrative fields, so lets not rain on their parade.
And that's the point. Once we make a choice, we must accept the consequences. The article indicates there was some sort of agreement between life and students that says "If you study hard and get an advanced degree you won't have financial troubles." Since that wasn't the case, the world seems unfair. There is no such agreement. I'm not raining on the parade of students studying things that interest them. I feel strongly that their studies are beneficial and they become better people and better members of society because of them. But they were never promised financial success and not having it is not a breach of contract in any way shape or form. That's why this article rubs this crowd the wrong way.
I was all set to double major in mathematic when I got married. When my wife and I had our first kid I decided to finish up a Computer Engineering degree and enter the workforce rather than take an extra year to finish the math major.
Sometimes you have to find something you enjoy enough. I absolutely enjoy programming, but it still doesn't come close to how fascinating I find number theory.
Everyone has options, and they make (or should make) their choices fully aware of the likely outcomes.
