Depends really. Pick something like physics, biology, maths, or IT etc etc, and yeah you'll likely be able to find somewhere to work as long as you put the effort in. It's about picking something that's actually going to serve you later on in life, if you pick Art, Philosophy(wat?) or surf science(again, WAT?) then its not worth it beyond the social side. Ie you picked a course that has no bearing on anything. Not that I'm saying Art of Philosophy (surf science can fuck off) don't have their place, but they're both subjects that you really shouldn't be going to University to study for three years and then expect to get a job out of them.
Similarly there are a lot of "fad" courses, like psychology is at the moment, A LOT of people are doing it, which is a shame because there are some people that really are into it, but they have to compete with a ton of other people who just sort of vaguely picked it.
Furthermore, don't pick a course you don't really know much about for FUCK sake. During my first year at Uni doing Video Games Development half of my class had never touched a computer before, I swear, and because of that, we had to waste a load of lessons to make up for these people. WHY ARE YOU HERE? You don't see me going; ooh I think I'll do Brain Surgery! I've not done biology since GCSE but I'll give it a go, it can't be too hard right?
