"Each year, every laboratory produces a new crop of Ph.D.’s, who must compete for a small number of jobs, and the competition is getting fiercer. In 1973, more than half of biologists had a tenure-track job within six years of getting a Ph.D. By 2006 the figure was down to 15 percent."
I would claim that science requires some basic integrity in its practitioners and if an institution is treating it's members as so many throw-away resources, it is hard to expect those members to move ahead with great idealism. The model of every desperate competitor watching every other competitor seems to be the replacement for model of science as a high ideal. I don't see it working out well.
