Can You Study 2 Majors At The Same Time?

After I graduate from high school I wanted to do Archaeology but I've been doing quite a bit of research and it doesn't pay very well and there aren't many jobs but it has always been my dream to do it and get a PhD in that career. I also want to do something in financing because I know I can do a lot with any type of financing degree. Is it possible to do both those majors at the same time? Even though I know it would be difficult I am willing to do it but is it realistic?
