This feels like a symptom of a society that has accepted the act of completely outsourcing child-rearing clashing with an event that makes that outsourcing impossible. Being able to work full time while comfortably having other people/institutions raise your child seems like a privilege. Now we are just seeing what happens when that privilege is taken away. I can't help but imagine there are a bunch of parents out there who decided to forgo full time jobs and careers to raise their own children shaking their heads and saying "this is how it is".
Being able to work full time while kids attend school isn't a privilege, it's often a necessity, at least in many parts of the US.
Until relatively recently, supporting my family of four required both my partner and I to work full time. Raising kids is an expensive endeavor. Luckily, I've advanced in my career enough that I can now support my family on my own.
You are right, but I think you are missing the context of the article. While I'd like to avoid generalizations, most employees of SV tech giants aren't exactly struggling to get by. These are employees that can now work from home (another privilege many parents don't have) a high paying jobs - the ones that usually afford them to be able to hire childcare so that they can work through the day.
