If not that, the only other answer is the parents. Are you as parents willing to give your kids a better childhood at the price of throwing away 10% of your career, with no (monetary) compensation? I suspect, very few. (More will do so with only one parent giving up the years.)
"You can have it all" is a lie. You can't both have a wonderful career, a great marriage, and give your kids all they need from their parents. You can't. What we really need is for people to stop believing that "having it all" is possible, and therefore expecting that someone owes it to them. Instead, people need to prioritize and choose what they want out of the tradeoffs that reality imposes.
