>Are you suggesting we should allow less people to graduate in order to fix the problem?
Yes of course. As per "The Mythical Man-Month"[1] adding more people to a project doesn't speed id up - quite the opposite, slows it down.
Right now we have huge overhead in training and communication. Low s/n ratio follows. You can fix that gatekeeping science a bit better - pick more talented, better educated, harder working candidates, and train & finance & supply them better.
