It's a very good point about women in the trades, and it's really a missed opportunity to date.
I do think that one of the best ways is actually to get into the high school system. Around junior high school age is the age where the research shows that young women start to differentiate themselves from the sciences and also some of the more practical nature of work. Programs and policies that allow for education of diversity, particularly around the trades, at that time is very important. I think of introducing courses for young women that might include a week in a welding shop, a week in an automotive shop; those types of things are unbelievably valuable.
Bring your kids to school day is a program that can be very positive, but it has not had a lot of traction at the moment, and it's unfortunate because allowing a young woman to see how much fun it is to be a welder or a pipefitter or some other electrical trade is really quite critical.
I think as you move along through that, keeping the opportunity for them to be exposed to role models through high school is very critical. Who are the tradeswomen who can come into the school and be with them and take them to their shops? It's very important.
