Society should end the concept of gender roles when it comes to anything. Let us allow a person to become an individual of his!/her choice. To add, there are more male engineers than female, so what's the fuss? There are still female in this field, despite of male outnumbering them, they still function not according to their sexuality but to their job. Same thing with investments, if they are not into such activity, then why should we force them? This idea is the reason why there are still people being oppressed with regards to things that they want to do and things they want to be.
Men and women alike have the opportunity to be in the position they want. jobs that are dominated by men can also be done by women and vice versa. It is not a matter of sexuality, but rather how the quality of work needs to be assessed.
anyone is free to choose his job, not limited to gender differences.
