This "temporary shortage" has been ongoing since the 1970s.  Like nurses.  That's a fact (BLS).  There are 4 MILLION available trade jobs that go unfilled every year (Mike Rowe).  And males who go to college only earn more in the STEM fields, and only if they complete their degrees (something else that's a huge problem - men are dropping out of college at twice the rate women do).  The problem is that you are conflating a "job", for which you are paid for your labor and time, with a "trade skill", a skill that will follow you over time and isn't dependent on someone else.  Women like jobs because they seem secure.  Men like trades because they are secure.
