Doing an Arts degree is one of the best choices I've ever made.
I majored in Linguistics and International Studies, but also studied Philosophy, Psychology, Religion, Bioethics, Human Rights, Gender Studies, Media Studies and Politics as part of that same degree. One of the things I liked most about the Bachelor of Arts was the freedom. I went to Monash, but I'm sure this is similar across the board: the possibilities are many. I have a few friends who also did a Bachelor of Arts at Monash, and our university experiences were entirely different - we studied entirely different things.
Is that inherently a good thing? Nah. If you know you want to study Science and nothing but Science, then sweet - do a Science degree. But for me, I didn't have that sort of certainty exiting Year 12. I was interested in a lot of things, and thought that humanities of some sort probably suited me best, but didn't have a
passion as such. So I tested the waters - and I practically stumbled upon what
became a passion in Linguistics.
I'm thankful for having done an Arts degree - not necessarily for the content, but a) for broadening my perspective; b) exposing me to issues and topics I'd literally never thought about before; and c) allowing me to develop (predominantly written) communication skills in a way I honestly don't think I would have in other degrees. As with numerous but not all degrees, it also gave me the opportunity to travel, which was a genuine highlight of my four years at uni.
To answer your question regarding whether or not a Bachelor of Arts gets you nowhere:
I don't think you can make such a generalisation. I know people who studied Medicine, finished Medicine, and then floundered because they realised Medicine wasn't actually for them. Same with Law. Same with Science. Same with Arts. Same with Commerce.
Equally, I know people who have excelled with each of those degrees - including Arts.
A Bachelor of Arts gives you the opportunity to develop some extremely useful skills, which are often highly sought after. It's simply not the case that a degree will get you a job these days; more people in Australia are educated at a tertiary level than ever before. As such, one might argue the worth of the degree itself is diminishing, and potentially will continue to do so. What this means is that potential employers will very unlikely hire you because of your degree in isolation. If you have a Bachelor of Arts but aren't suited for the job, you won't be hired. If you have a Bachelor of Arts and are suited for the job, you will be.
If an employer looks down on a Bachelor of Arts as useless or inferior, trust me: you don't want to work there anyway.
If (and this is a big if) you think you'd be interested in studying a Bachelor of Arts, I encourage you to do so. FWIW, you can read more about my thoughts on Arts
here (parts are Monash-specific, but it's broadly applicable).
