It would be interesting to see how much the undergrads are making after two years (expected amount of time to finish the degree), and the masters after four (to finish the PhD).
And also, the variance in the amount of money undergrads make after 6 years, compared to the variance in the $ that PhDs make. Some undergrads could earn MUCH more money than PhDs, but it's also ENTIRELY possible that undergrads could fizzle out/make a major mistake and end up in a perpetual cycle of low-wage jobs (and this can happen to the highly intelligent too)
