My original response was to highlight that perhaps we shouldn't be elevating child-raising as a completely altruistic, society-benefiting endeavor. We're talking about a few tech companies, which is not representative of the U.S. (nevermind human civilization).

"Amortized value to society" seems a very one-sided portrayal. Why should I earn less than someone who has kids, when skill/experience/contribution are equal?

Being a parent is a personal choice in today's day and age, especially for highly-paid tech employees. Let's not paint it as some altruistic gift to mankind.

Because your contribution later in life is likely to be negative. You will be putting strain on social security, medical insurance, etc. A strain that is uncompensated by the contribution of your kids in their prime earning years.
