This was a big question for me aswell before I began uni, started out majoring in accounting, then economics Im now doing B Bus(Finance/Banking) with honours year. I think it depends on what you want to get out of it, for me I want to work in trading or risk management in the banking industry, and although accounting is a great degree to have I was just far more interested in financial markets, plus I am always learning of ways to build wealth through the content of my degree, so perhaps I wont need to work for too long!
I would say
go with what is interesting otherwise whats the point? as others have said you can always make money, I just find Finance faster paced, more creative and a higher possible return on investment (of course this implies a higher risk that the expected outcome will not be realised
)
