Why should the vast majority, or even a sizable fraction, of fields not have a gender or race balance even remotely approximating the balance of the general population? Is it not a 'should' but merely 'it's okay if they do'? If the balance was in the other direction and men or white people were being intentionally denied jobs, would that be okay?
Should it be OK for other things to be unbalanced? Should it be OK if 60% of black people can't get houses but only 10% of white people have trouble getting homes? Should it be OK if 90% of asians are turned away from emergency rooms but only 20% of mexicans are?
You can argue that race/gender genetic differences play a role but it's kind of hard to explain away the widespread imbalances here just based off DNA.

>Show me one field (that does rely on the person's ability not looks) where there are more women in the higher ranked positions and more men in the lower ranked positions.

You're implying – and your argument rests on – that right now, women and non-white people are being intentionally denied jobs due to their gender or the color of their skin [1], and that this is a widespread phenomenon [2]. I would really like to see some hard evidence for that claim.
[1] As opposed to their qualification or other directly relevant criteria.
[2] I'm assuming you mean in the US, or at least in the Western world.
If you believe that racial discrimination in hiring (or otherwise) is made up, you need merely perform a google search to find many reputable articles and papers on the subject. Feel free to educate yourself.

"Now the plaintiffs can request access to internal Google documents to try to support their allegations, which also include some people being “denied employment because of their actual and perceived conservative political activities and affiliations, and their status as actual or perceived Asian or Caucasian male job applicants,”"
There are myriad examples of this sort of allegation from the last decade, it's not hard to find them. They've been discussed here on HN.
