You do get a better paying job on average if you complete hold a highschool diploma over an employee without one, i believe its something like 30 - 40% more, the same goes for a degree holder you make a certain percentage on average more than someone with just a highschool diploma.

If you arent taking business, you probably wont be learning about ways to make money, my business course has already helped me set up a business and begin its operations.
