Well, one easy answer is of course to point out that apart from the huge increase in the number of students $-$ it would actually be interesting to have reasonable figures on the time spent teaching per-student, in comparison with pre-1963! $-$ the government(s) have switched the emphasis to research by decreasing the amount of funding available for universities and rewarding private initiative to obtain research money, eg from industry, or simply making the process of funding increasingly competitive!
