<p>Since cash flow is a sticking point, and if OP’s friend is intrinsically interested in pursuing business management, Ross is a great choice.
Although Yale, over long term (30 years) horizon provides a slightly better return on investment. $954,300 (Yale) versus $901,400 (Michigan).

IMO, high levels of debt to attend Yale is not worth the mental anguish. Save the money, work a few years & attend Yale (or Stanford, Michigan, …) for MBA. Get the best of both worlds!</p>
