As many stated, it really depends on the major you're going for.
I'm in the sciences, and will get a BS, get a job...and then later probably work towards a masters. And the whole point of it is that you rise up the tier and get paid more the higher degree you have. It's really less about learning and more about the piece of paper.
You can easily learn more from experience than a year for masters (which is usually how long it takes). I know many people around me who are going this route because it's the smartest one...and others who are completely ignoring the masters because it's pointless to them at the moment - at least.
I would recommend you find a lot of people in your field, people who are in clubs, and your professors, and see/hear about their experiences and recommendations. The best people who can give you the best guidance are the ones who've been through it.
Also: the convenience of getting a BA/BS then getting a job is that you not only get experience, pretty darn good pay, but occasionally the company you work for will PAY for you to go get your masters. Which means, not only do you get a good job, but getting your masters becomes..literally priceless (no price, for you, lol).
But yeah...talk to people in your field because every field differs.
Like for example, I have a few friends who didn't even bother to get a BA/BS in art/art new media because it would actually put them in debt and not pay off at all later on, because in the art field, having a portfolio outranks all degrees on paper. While at the same time, I have another fiend who is studying art history - but for the purpose of becoming a college professor, so for her...she needs to get higher education (AA not enough).
All professions make a difference, and even WHERE you want to work and WHAT you want to do make a difference on the degrees you want to get.
In this day and age, your degree gets you through the resume process....but experience and connections get you the job(more often than not, this is the truth -- I know enough people in the hiring committee to know that they get so many resumes, and experience and connections make it so much easier on them to pick a person). Go out there, get a degree, get experience, and meet new people. Then you have a better chance of being successful after you finish college/univ.
