I mean, I come from an excellent pedigree, too, top 10 undergraduate, top 10 grad school, and I currently work at a place where my boss is a nobel laureate. (He makes at least 250k, according to the place's 990 forms)
However, my going price gets diluted by the idiots running around with rubber-stamped PhDs. Maybe there needs to be a 'brain drain', if we can drain those people selectively somehow.
(The bottom line is that the money goes to administration costs as mentioned, leading institutions to expand to stay relevant, thus building more buildings and hiring more PIs with full expectation for them to be funded via grants. Meanwhile, the average researcher's earnings are mostly unchanged.)

The part that is always unclear to me is: there is lot of evidence that research/university budgets are growing at a high rate. Where does all that money go to. It doesn't seem to go to the people who actually do science.
That seems to be the fundamental problem here.
