Almost certain OP is referring to the fact that nurses and teachers are not well-paid or respected in the US, which I'd like to note as well. Despite this, Public Health as a pseudo-STEM major nearly ranks with STEM fields in general for majors seen as "workplace-ready."

Maybe there are too many English majors (I honestly think the supply of careers is too low). But I think the "supply is greater than the demand" is possibly now more an explanatory argument for unemployment rates for Engineering and PT and other such quiescent majors. Certainly there are plenty of Ed majors for a field whose workers fled at pace earlier this decade.

Let's assume I'm teaching 25 or so Engl majors right now in a class with publishing as its central focus (hypothetically) at a state school. The students would neither be able to define "small press" nor name the big 5 - even the ones who just came back from AWP. The linked piece, I think, correctly names the romanticized vision of publishing that is divorced from understandings of the cost of living in NYC. I don't also think that college majors are actually all that itchy to get into editorial, whether or not they're all and every single one applying for the same pool of jobs.
