Everything you have said was true 40 years ago yet boys were the majority of University entrants then and are a small minority now. Boys represent an even smaller portion of enrollments now than women did 40 years ago.
As I'm sure you know women are a tiny majority over all and at the university entrance age group basically not at all. You know that so why are you throwing it up? 
Why are you so eager to try and deny the problem exists? Seriously, why is it so difficult for you and other deniers to admit the problem exists?
