The title of the article says "English majors", but the body says "Liberal Arts majors".

"Liberal Arts" isn't a category of undergraduate major. It is it's own category, which is generally only offered at 'Liberal Arts' colleges which offer only that major. However, if you take 'Liberal Arts' to be a 'category of categories', it could potentially include:

Humanities - English Literature, Modern Languages, History, and Philosophy
Social Sciences - Anthropology, Economics, Geography,
Political Science, and Sociology
Creative Arts - Fine Art, Theatre, Speech, and Creative Writing
Sciences – Astronomy, Biology, Chemistry, and Physics

Ok, nearly any major that existed before 1940 apart from Mathematics and Engineering.

What did the survey say exactly? Well, first of all, from everything I can tell it only includes 4 states, Colorado, Michigan, Texas, and Wisconsin. Not exactly representative, probably, but what schools are included?

Well, I've never heard of any of those schools, but whatever, maybe most people go to schools I've never heard of so that's not exactly evidence of anything.

I didn't want to go through every school, so I just picked University of Colorado, Denver, since it seems like it's probably one of the bigger schools?

I used https://factfinder.census.gov/faces/nav/jsf/pages/searchresu... to compare all the majors. I couldn't find a single non-STEM major that had better incomes than even a single STEM major. I assume this is the dataset he is taking his data from since he links to it.

So I guess what I'm saying is, this article seems to be predicated on a tiny dataset from a few select schools from a few select states, does not include flagship schools, (in fact it seems to only include 3rd and 4th tier schools, no Anne Arbor, Reed, University of Portland, University of Oregon, Rice, UofT Austin, Texas A&M, U of Wisconsin, Lawrence, Milwaukee School of Engineering, Marquette, etc etc etc.

So before you debate 'what this means' you should know that, based on the above, it means nothing, and no general facts can be drawn from it. I couldn't even figure out what methodology he used to come to his conclusions (if any), or even what he means by 'liberal arts' since that's not a category in the data.

All that, and the data I could find completely disagrees with his analysis, and in fact shows the complete opposite.
