It seems like people have started thinking of "STEM" as some label that means "better or more worthy of focus than other disciplines and careers." That's probably because of the push to put more focus on STEM fields, especially in primary education.
There's nothing wrong with non-STEM fields, and I feel like this push to include more and more things in the label implies that STEM means "good" and non-STEM means "bad." It reminds me of the common recreational debate about which things qualify as "sports," as if any activity that isn't considered a sport is somehow worse than activities that are considered sports.
