Fuck that. I majored in math, and even got a graduate degree in math. I would rather see somebody go into a field like mathematics because they truly enjoy it than because they heard that the job is cushy and pays well.
If you pursue a degree, it should be in a field you enjoy. If that's English, great. If that's music, awesome. If that's theater (a field I seriously considered), fuckin' A, buddy.
It's not like STEM degrees never suffer from problems that so many pro-STEM circlejerkers criticize non-STEM degrees for having. The employment and wage numbers in many (even most) STEM fields are better, but it certainly isn't universal. I taught a lot of chemical engineering majors (at a school whose ChemE department specialized in petrochemical processes) back when oil was $100 per barrel. Guess who is having a hard time finding employment these days, despite having a degree that was considered a "golden ticket" just two or three years ago?
Your employability in any field will almost always depend on the market forces of the field and your ability to perform within it-- STEM degree or not. There are some exceptions, of course, but that's the general rule.
Everybody seems to jump on the pro-STEM circlejerk because the degrees "pay for themselves" more quickly in terms of starting salary and promotions (that's not how I value a degree, by the by, but let's pretend that it's a good measure). The raw numbers supporting STEM degrees are correct, but that doesn't mean we should steer all students of every interest and temperament into STEM fields. An engineer who hates his job but sticks with it because he has a mortgage to pay won't innovate nearly as much as the engineer one office over who thinks she's the luckiest person in the world for getting paid to do what she loves.
Instead of focusing on getting lots of money right after graduation to "pay" for a degree, you can also work to decrease the cost in the first place: people think I'm nuts when I say this, but a good community college can be a fantastic place to learn, often for a fraction of the cost of a university-- especially since many states have guaranteed-transfer programs that help ensure that you don't have to re-take classes at state universities. You can get students involved with industry partners earlier in their education (not in shady, slave-labor "internship" programs that simply exploit students, but in honest-to-God work-study programs and the like) that provide genuine experience and make students more valuable to employers when they graduate, and sometimes help pick up the tab for related coursework.
In the end, though, I don't think a college degree-- especially as its employment value has diminished even as its costs have increased-- is best viewed as a purely economic transaction. College is more than an extended job hunt-- it's a chance to explore, to be exposed to new ideas, to test your personal boundaries, and to consider your personal values. I think you should study what you love, but be cognizant of the economic realities around you. Getting a degree in criminal justice or drama (two of the lower-paying fields) doesn't make you an idiot. It does mean that you're likely to be paid less, but if you can make a living wage, that's not so fucking horrible.
(The argument that you can't make a living wage from certain degrees-- or that college degrees in general are becoming less valuable even as we push more student through college at higher cost-- starts to move us out of the realm of individual choices and into matters of public policy. And that's before you get into the educational loan horror show. I'm definitely not going to open those cans of worms.)
tl;dr: STEM is fine if you like it, but the pro-STEM circlejerk treats college as a purely economic transaction, ignores a lot of human factors, and seems to focus exclusively on money as the only measure of success. Funneling uninterested students into STEM fields is a bad idea, and a superiority complex doesn't fucking help.
