The last high tech engineering entry-level job I hired for offered 4 positions.  There were 160 applicants, but only 12 applicants were women, or ~8%.  We hired 1 women for one of the four positions, or ~25%, as her skills and experience stood out from the other applicants.  This is a big leap given the sample we were given to work with, but it was not possible to have a 50-50 split because only that woman out of the 12 met the qualifications.  If women want to work in high tech or want high paying jobs, then study, train, develop skills for, and apply for these jobs.  It's that simple.  There are no educational boundaries, no barriers to entry or advancement for women in high tech.  Complaints from society about a 'gender gap' are nonsensical.  The evidence shows that women, on average, simply choose not to work in fields that are the highest paying or that traditionally have been dominated by men.  In my experience, it's all on women to fix the gender gap.
