I've got a degree in chemistry and it's really hard to find a job here (Poland) that would let me live with due respect as I really worked hard to get a degree, it's not easy to study chemistry, it's a very difficult and demanding. The salary is like the minimum salary, i.e. ~1 500 PLN ≈ 284 £ ≈ 446 $ . Sure, it's Poland but I know of no job with a salary worth of 284 pounds a month in the UK.
I also was in the UK and I couldn't get a job there as a chemist either. It's kind of a weird situation as when I started studying chemistry, there was supposed to be a shortage of chemists.
Being a lawyer seems boring to me but if you've got contacts, you won't be poor and it seems all this world is about is money. That's why I started studying again and chose IT because this is going to be up-to-date any time. Though I'm at the age when I should rather think about settling somewhere, meeting a woman of my dreams, getting a job etc.
Anyway, I don't really like what I study right now. I'm serious. I'm just interested in programming, web design, and computer graphics but again I had to choose "systems and networks" as my speciality because it's going to be more payable. I've got a lot of lectures that can bore me to death. Electronics, metrology, power engineering, some crazy physics shit I don't like at all. But I still love chemistry despite all this time and if I only could, I mean, if I saw some hope in it, I would prefer to work in a laboratory than be an administrator of some network.
You want my opinion? You can have both. But first get a degree in the one that you know you will have job after leaving the university. Then if you still have time and motivation, you can continue with the other field of study.
I kind of lost time because I was interested in something. It should be prohibited to be interested in anything in a world like this.
