I see this as an attractive way to establish an apprenticeship. At least for software engineers, it is rather common to move around every 2 to 4 years, which makes it hard to maintain and nurture a mentor relationship.

If I were to invest in a student, my advice and attention would help secure my investment and would probably be worth more than the principle to the student.

This type of Money and Mentorship scheme would be especially valuable for poor, minority, or first-generation college students that come from a community or family unable to offer them informed direction or advice.
