No. That is the not real problem here.
The problem is a certain things have a very high barrier to entry. Getting into such things requires over the natural amounts of persistence and other myriad life skills for which you need a certain level of biological independence(like not having kids for example).
These barrier to entries vary with each profession. They are higher for the cool jobs, like the CS ones. Most of these career type jobs where continued work is required. Taking long breaks, asking for lesser working hours(While having colleagues at office who would be pushing 15-18 hour workdays) and other such things makes you a bad worker even if you were to somehow work hard and gain initial access. Net result is people feel they are better off doing things where their contributions have some meaning than having to compete with 16 hr shift workers against whom you are set up to lose by default.
This is the whole difficulty with the diversity problem. There is a inherent assumption that things be made easier to accomodate minorities of all kids. Whereas doing well in any profession requires the exact opposite. Harder the things, the better you get by doing them. But that also means, people who are not tough enough for the job get filtered out every iteration along the way.
You just come down to the point that you can't make people do, what they are not ready to put over the necessary efforts to make happen.
