What should I do at uni?

I am questioning what to study at uni, initially I was set on studying biology, but now I am less sure. After my work experience in a lab, I can't really see myself working in research / laboratory environment. I am concerned about graduate prospects from biology that do not require a PhD, and what other options there are besides lab work. In short, although I enjoy the subject, I am unsure whether I would be able to find an enjoyable well paid job after graduation, without gaining a PhD.

My second uni option is economics, which I have enjoyed studying at a level, and as far as I am aware has better graduate prospects.

I would be grateful for any advice!

perhaps jobs within finance or management? I don't really want to end up in science anymore, so is there any point to doing a science based degree - if I will move out of that field? I basically want to do a degree which will give me lots of options post graduation, as I don't have a specific career in mind.
