Exactly? It doesn't have to be a BA, but (very) often is.
The only reason you omitted Education was because it doesn't support your "argument"
ERRRR where the fuck are you getting that "very often", people who have careers in education have a BA?
Furthermore, I'm pretty sure Brendan was only bolding the salaries of the jobs which are exclusive to people who hold BA. If you look in the maths thread he didn't bold education there either.
Just drop it man, you're more annoying than Brendan ever was. It's like you stalk his posts, I've never seen you post in any other threads besides those threads Brendan posts regarding Arts degrees, but that may just be because I don't read every single thread on the forum.
