>Actually, the chart shows a pretty damning story for selection bias: despite all the selectivity of schools, there's no sign of improvement in returns for more selective engineering schools. But since we're talking about ROI and not salary, you very much want to get into the most expensive, most selective engineering schools. If I invest money in bonds these days I'm going to get less than a 5% return - if I can get a 12% return I want to invest as much as I can borrow.
