Why does everyone seem to think finance is the dream job? The big money's gone now from Broking and Trading unless you're the best of the best (in which case the degree you study is hardly going to have much of an effect), and I'd say that 80% of the people I know (family friends, my dad was a broker) who did it seem to be (overweight) divorced alcoholics. I hardly saw my dad until I was about 10 when he started cutting back on the hours, he'd leave home at 6 and get back around 1-2 (after meeting clients), he was constantly depressed or angry, and the happiest I've seen him in his working career is when he quit his job to work as a shelves stacker for a year.
I'm only in second year at uni and already my two friends who do physics are joking about their complete unemployability, I personally know 8 chemist graduates who transferred onto my course (2nd year of a 5 year degree - Chem Eng) because they realised that unless you want to do a phd you just end up as a lab monkey, and that seems to be a the fate of a lot of people who study biomedical sciences as well.
The others are good in that they directly lead to a job, but this idea that generic science degrees are a golden ticket to a well paying job and are much much better than other humanities degrees are utter delusion - I'd certainly take a IR undergrad degree over a chemistry or physics one.
