The problem with quotas in any job whether it be a male dominated field such as pilots or a female dominated field such as nursing, if you encourage applicants on the simple fact that they need to fill a quota you're not necessarily getting applications from an equal pool of application.
It is a simple fact that different genders gravitate toward different industries. Even when there are concerted efforts from the state or private industry to change this fact, the genders in the long run tend to go back to where they have always been. Women are almost never carpenters. Men are almost never nurses. There is no natural 50/50 split to almost any industry today.
That being the case, if the entire pool of potential applications isn't a 50/50 split in the first place how are you going to get the best person for the job if you aim for a 50/50 split in the workforce but 90% of the applicants are men and 10% are female for example.
That would mean you would need to be an exceptional male candidate and a mediocre female candidate to be successful in a male dominated industry. Conversely you would need to be an exceptional female candidate and a mediocre male candidate in a female dominated industry.
Common sense would dictate that is a crazy notion to entertain however in today's world of PC craziness I'm sure there is a catchall word to shut down any discussion to the contrary. Modern society doesn't tend to deal with simple facts these days moreso they deal with the feelings based ideologies of the left wing.
