Funny, I don't see an effort to get more female roofers, plumbers, electricians, garbage workers, or any other male dominated professions. What makes this one so special? If women don't like a profession, then they don't go into it. Stop trying to force gender equality when it's not wanted nor necessary.
Seriously? If you lived in Seattle, you'd know there are statutes requiring that every government-funded project employ, at a minimum, some specific percentage of minority- and women-owned businesses when hiring contractors, roofers, plumbers, electricians, etc.
Washington State is a (poorly run) nanny state. I work at UW. This past month, in order to qualify for a $125 "wellness incentive" on my health insurance next year, I had to fill out a "well-being assessment" that, among other things, asked me multiple questions regarding whether I felt "empowered" at work. Based on my answers, one of the suggested activities I could do for credit (in addition to the more reasonable "eat five fruits and vegetables" and "walk at least 35,000 steps a week") was "meet with a mentor". Yeah, you guys can't even agree on a budget but you can spend money developing an overly-simplistic computerized system to pretend you're actually caring for your employees...
