Just in time for the end of the world

Revenue and spending would be a more useful measure

Many of the differences between men and womens preference in work can be explained by cultural expectations. That women are pressed into more caring societal roles, where men are often pushed the opposite way. That's not to say that are no inherent differences between men and women, on average men are stronger and as you say are therefor better suited to work on an oil rig, and an inate maternal sense may well make a woman more suited for nursing. However it's hard to pull these appart from entrenched cultural influences, which may seem natural, but at least to some degree are artificial and further move us from meritocracy.

But as for politics, this is a personable and cerebral field, traits upon which race and sex have, as far as we currently understand, no bearing. There isn't any inherent reason that a white man would be better at this than anyone else, and yet the majority of western politicians are white men. This is because of the historical inequality between men and women, and between different races, it is the clearest and most salient explanation for the phonomenon.

Also side note "white" and "black" are not races, there are innumerable races within these broad categorisations with different genetic traits. I find it unlikely on the face of it that there would genetic signals that link skin pigmant with cognitive ability or temprement, certainly not in a way that would affect ones suitability for different proffesions.

Exactly, you can say it as subtly and with as much sterility as possible, but ultimately falsly asserting that white men are just best suited to government is part of the deeply entrenched sexist and white supremicist nature of our society.

Well surely in a meritocracy you would expect a roughly even distribution between men and women, since they're fundamentally equally capable. If there is a large disparity between the sexes it would signal that perhaps the system is unmeritocratic.

Do they just kind of wing it for people who don't play an instrument?
