I agree people are weird, and their group interactions can be hard to characterize or understand. And this is a particularly contentious and difficult issue.

Let me try to summarize what I hear you saying:

There are demographic disparities everywhere between the general population and any given field. Some of those disparities may be due to discrimination, but to what extent discrimination may be playing a role is hard to determine. Companies (for the most part) aren't engaging in blatant discrimination. Some of the disparity is likely due to career choices that are in part a result of how people are brought up and their educational opportunities. As far as education goes, no one should be deprived of educational opportunities due to environmental factors.

Is that an accurate representation? I don't want to be putting words in your mouth or creating a straw man, as that serves no one. Please do correct or improve my summary where needed.

I think your point regarding educational opportunities is particularly important. How do you think this can be improved, in as far as decreasing disparities due to educational opportunity environment differences?
