If I were going to do it today the first choice would be business degree and MBA from Harvard or Yale. I'd be willing to borrow what it took, because the payoff is there. In the US today this is the ticket to the C-Suite.

If I couldn't get in I'd try to get an ROTC scholarship for as prestigious a place as I could manage and graduate without borrowing money. Either business or liberal arts, though the latter case is a minefield of worthless programs, so it would require some research.
