And a BA isn’t worth much regardless. Half the people I knew in college now work at coffee shops.
A general good rule is what when you see someone do something, there’s probably a, if not good, understandable reason for it.
I agree with everything you said but just wanted to point out that in the comment you responded to, “BA” means “Business Analyst”, whereas in the sentence you wrote that I quoted it seems that you took “BA” to mean “Bachelor of Arts”.
In this case, presumably a middle-class kid who was fed a line that going to college is the way forward. They were probably decent but not outstanding students who went mostly because that was expected and got a A of Arts degree because the BS degrees are miserable.
Motivated folks can make that BA work, but your barista was probably going to end up there with or without a Bachelor's; the BA just means they're promotable, or may be able to break out of that place later.
That you think that you understand someone’s reasons doesn’t mean that you have to agree with or not think there’s are better ways.
