The goal is NOT to "inspire girls", the goal is to make the job sector reflect the population, no?
for feminists it seems like only the nice cushy office jobs needs to reflect the population, not the dirty labour
the problem is to identify what the barriers are and how to actually get rid of them. lack of inspiration can be a barrier.
The biggest barrier of them all for both men and women is that young adults will look to similar aged and gendered peers when choosing career paths. Such choices generally provide a feeling of safety which provide protection against setbacks and doubt (something most student and later professionals generally face multiple times at some point in their life). This concept is a major aspect of gender equality paradox, which predict higher rate of gender segregation with fewer barriers.
The most effective way to get rid of those barriers is to create alternative forms of protection that give similar effects. Mentorship programs has shown to be very effective substitute for both women and men, but they are costly and do not fix the initial problem when young adults chooses career paths.
Sweden has public data on gender segregation, and they provide an additional risk factor of gender segregation. Career paths that has natural points for segregation has generally higher rate of gender segregation. Examples of those are teachers who can first segregate on age/educational level, and then further segregate on subject. An other is nurse, doctors and other health care specialists, who can later segregate further based on specialty. Give people multiple chances to self-segregate based on identity and they will do so.
but i think we can do more with mentorship and go beyond its perceived limits. however getting there takes us to rethink education as a whole.
there are a few aspects: for one i think everyone should have a mentor at least for the first few years of their career. that should be part of our education system. for example, every university graduate should be required to mentor at least one new student. every university student as well as trade apprentice should mentor in highschool. etc... in the montessori education method older students always teach younger ones, so mentoring at a higher level is really just an extension of that.
this would obviously be easier to ask in countries where higher education is free, because then its fair to ask for something back.
from these, mentoring in highschool is probably the most important because that's when careers are chosen. i remember that time, and i remember being all alone with my choices. i really would have loved to be able to get more insights into the potential careers that i was interested in.
However, in the real world, a female CEO or President is much more likely to inspire girls to work towards those roles, compared to a model female plumber.
They call it "glass ceiling" not "glass floor" for a reason.
Those feminist organizations are definitely hypocritical, no question about that. That does not necessarily mean they are doing anything "wrong", according to how the world runs. I wouldn't blame them for not doing anything.
All that said, I think you bring up a valid point that people almost never talk about. But that's as much as it's worth.
