An English major is NOT getting into a STEM Ph.D. program, no matter what.
Even if they were, job prospects are worse for STEM Ph.D. holders than for MS/BS holders—there are far fewer jobs that require Ph.D. level qualifications outside of the professoriate and academics, and for Ph.D. holders in particular, employers are absolutely loathe to hire overqualified people.
Inside the professoriate and academics, the job market is historically bad right now. It's not "get a Ph.D., then become a lab head or professor," it's "get a Ph.D., then do a postdoc, then do another postdoc, then do another postdoc, then do another postdoc, really do at least 6-7 postdocs, moving around the world every year the entire time, and at the end of all of that if you've managed to stay employed at poverty wages using highly competitive postdocs that you may not even get, while not flying apart at the emotional seams, you may finally be competitive enough to be amongst the minority of 40-year-old Ph.D. holders that gets a lab or a tenure-track position, at which point the fun REALLY begins as you are forced onto the grantwriting treadmill and feel little job security, since universities increasingly require junior faculty to 'pay their own way' with external grants or be budgeted out."
And that's INSIDE STEM, which this person is almost certainly likely to be uncompetitive for as a B.A. holder trying to get into graduate programs.
Much more likely is that with great grades and GRE scores they'll be admitted to a humanities or social sciences Ph.D. program, with many of the same problems but with CATASTROPHICALLY worse job prospects due to the accelerating collapse of humanities budgets and support on most campuses.
Ph.D. is absolutely not the way to go unless you are independently wealthy and are looking for a way to "contribute to the world" since you don't actually have to draw a salary.
For anyone with student loans, it's a disastrous decision right now, and I wouldn't recommend it.
I say this as someone with a Ph.D. who is on a faculty and routinely is approached by starry-eyed top students looking to "make the world a better place" and "do research." Given the competition out there right now, only the superstars should even attempt it, and then only if they're not strapped for cash. Hint: If you don't know whether or not you're a superstar, you're not.
I think in a decade I've strongly recommended that someone enter a Ph.D. program once, and greeted the suggestion favorably maybe three times total, out of thousands of students, many of them with the classic "4.0 GPA" and tons of "books smarts."
In short, I disagree strongly with the suggestion. Unless you absolutely know that you're competitive already on the academic market, DO NOT GO. Don't listen to the marketing from the schools; it's designed to drive (a) your enrollment and tuition, and/or (b) your cheap labor as a teaching assistant/research assistant forever once you're in the program. It's a win for the institution, not for you.
The easiest sanity checks: Do you know exactly what your dissertation will be about and what you'll need to do, in broad strokes to conduct your research, as well as what resources you'll need? Do you already have personal contact with faculty on a well-matched campus in a well-matched department that are championing you and that want to bring you in as one of their own students/assistants?
If you answers to either one of these questions is "no," then while you may be offered a position somewhere, you will be on the losing end of the deal and would be naive to take it.
