Back from SfN. People still don't understand that the trendy motto "Limit the numbers of PhDs" inevitably comes together with "Make it harder to get to a graduate school".
Which, in turn, means "Make GPA mean more than it does now" (aka "No way back", or "You have only one chance"). Which would totally screw "non-traditional candidates" of all kinds, as well as "hesitant candidates", such as women, minorities, first-generation scientists, converts from other educational paths, people who had a baby, people who took some years off away from academia, etc.
The numbers are not the problem; it is the training program that should be improved (and there's more than one way to do it).
