Look, I’m an uneducated republican and even I can see what’s wrong with your argument. Or at least one thing.
The alternatives aren’t “give up” or “create a government program.” There is a whole lot in between there. Starting with our own selves. For example, up thread, there was discussion of receptionists and file clerks not breastfeeding in what I perceived to be an unkind way. In many professional firms here in New York, those positions are filled by women of color. If a person is aware that the women with whom they cross paths aren’t taking beneficial steps, then maybe offer some proactive support? Such as asking a woman getting ready to go on maternity leave if she has the support available to pump at work. Suggest lunch and learns where all women are welcome with guest speakers on important topics. Many women who have already made it are utterly shocked to find out that others down the ladder don’t have the same perks/opportunities/support that they do. Ask. If you’re an executive/partner/up-and-coming woman, why not inquire about whether benefits available to you are available to all women in your company/firm? And if not, are you ok with it?
I volunteer as literacy volunteer. My kids are now college educated (!) and so I can support the families I work with in making sure that their kids are on track to meet high school graduation requirements, know how to file a FAFSA, know how and when to take the SAT.
Point being: government bureaucracies that coerce others’ money isn’t the only or the best way to get things done. Each of us has a choice and if a particular issue matters to us, then we need to do something about it. Over the years, I’ve tutored more than 1,000 people and that has made a difference. Time, effort, role-modeling all matter a lot.
And here in the US, I don’t think genetics matters nearly as much as you do, since so many people are so mixed race it would be impossible to sort things out. I will agree that culture plays a role to a large extent. As I’ve stated before and been criticized, some immigrants coming here from indigenous cultures have no history of literacy in any language and don’t speak English or Spanish, so they will have a harder time. In their own languages, I think they could be very successful. For most, the ability is there.
