>what are the best majors for someone who wants to become a banker
Almost anything as long as you've got a degree (preferably from an impressive school with an impressive GPA) and a basic understanding of financial theories, economics, and accounting.

>businessman
Too vague to answer.

>economist
Maths with some econ or econ with lots of maths.

Arguably, best business school majors are accounting, finance, econ, operations management, strategy, and (business) analytics if you're looking for lucrative expert field jobs (such as consulting at a revered house).
