Genetics is the biggest advantage I agree.
But family stability and aspiration is more predictive than family wealth.
That is well known.
Cultural values: interesting you presumed I meant white families. Asian and African cultures are actually out performing 'white' culture in many ways.
Cultural cache means world experience and connection. Cultural capital. The white middle class have had an advantage with this but that is going to disappear within a generation I think.
Yes I do think that there will still be differences at a population level between the interests and choices of men and women even if we had no discrimination or socialisation.
Obviously there are skills men have more of. Anything to do with strength. More inclined to risk.
Biology - if you think that's just discrimination you're not much of a feminist.
Disadvantage doesn't mean the same as discrimination.
Geography - lots of evidence for differing interests and skills and aspiration based on geography.
Each of those obviously impacts outcomes and makes understanding discrepancy really complex.
I think discriminating against people at employment isn't the way to address discrepancy. It's immoral, won't work and will have negative outcomes.
