How? If I interview a bunch of people for programming positions and pick the 10 best men and 10 best women, which group do you think will be best? Statistically I have considered several times more men than women, so the male group will almost surely be stronger. The only way to avoid this is to intentionally pick bad men, or if I just randomly ignore 83% of their resumes.
It's just looking for people who are better than (some arbitrary skill level).
More men than women could bench press 160 lbs, but if your hiring bar is 'we hire people who can bench 160 lbs', you can trivially find as many people from either gender as you want.
Also, if you are buying a car with the goal of being able to accelerate from 0-60mph in under 4 seconds, and you have to choose between two cars priced exactly the same, but one can do it in 3.9 seconds and another one in 3.1 seconds, why would you pick the 3.9 car over the 3.1 one, even though the 3.9 one meets your requirements of under 4 seconds just as well (assuming all the other relevant characteristics are equivalent or about the same)?
Also, just because you have a goal to aspire to doesn't mean you can realistically meet it. Suppose if every high achiever in a school wants to be valedictorian, but only one of them will make it. That in itself doesn't mean it's a pointless goal.
