Business degrees generally encompass management and economics, and soforth, and, at their best, serve as effective sorting mechanisms for populating corporate America (though they are doubtlessly less useful today). They'd also be fairly right-leaning, if anything, for the purposes of this analysis. The fake/gay degrees I included were social science and psychology, which are objectively worthless majors unless you're one of a very small handful of competent psychology people (at that point, you'd major in neuroscience, though, and be counted with the med students).
