Something like this might be a three- or four-course sequence that I suspect would make college graduates much better off out of school. And maybe some students would decide to switch majors, out of selecting a more financially viable path to follow.
For that matter, make this a sequence of courses in high school. Or both high school and college. Some high school students may decide they don't need to go to college. Other high school students may decide that they do need to go to college. I had a class in high school that covered elementary personal finance, like how to manage a checking account and how to do taxes (by hand, on paper!). While I'm happy to have studied some geometry and read To Kill a Mockingbird, personal finance was probably the most useful high school class I had.
I respect patio11 for sharing what he's learned. Remember, he used to work 80 hours a week for a junior dev's wage, and now he has crafted a more comfortable, self-determined lifestyle for himself.
