<p>Top salary is a terrible way to measure a school. Yes a good school will make, in general, slightly more money for its grads, but it is also largely regional. CalTech, for example, gets helped by the fact that a lot of the graduates live in California where cost of living is very high, and thus so are salaries. Conversely, Michigan grads would be more likely to live in Michigan where salaries are lower due to lower cost of living.</p>
