I liked to think about taking in half the number of PhDs but increasing their salary, focusing only on applicants that can realistically produce. Or even better, shortening the PhD to 3-4 years, forget the salary altogether, and turning it into more of an apprenticeship, with the postdoc being the workhorse of academia.
