This is a loaded question. "society should value" and "pay more" are separate arguments. By agreeing to the first I'm not agreeing to the second. I think society should value taking time off to raise children, yes. However, I don't think that society should value a corporate attorney doing this more than a public defender doing it. To do so would value raising children unequally. A universal basic income with an additional stipend for child care would be one solution that captures this difference.

Okay, then we are no longer talking about paid time off and we are no longer addressing the trade-offs involved in taking time away from a lucrative career in SV.

Which is fine with me, I don’t think that’s a problem that needs solving but you and others in this thread had implied otherwise.
