Let's put aside for a moment your extremely broad characterization of the behavior of "all parents".

Do you not think that society should have an interest in ensuring that children are properly nurtured, educated, cared for, etc.?

Out of curiosity, is this what you think of your own parents as well?

Eh? If we’re in a “tech is a bubble” conversation then “the average American” conversation is out of the window. Tech workers earn way above the average. If you’re accepting that tech parents have the money to raise kids it stands to reason the OP would wonder why their peers aren’t also raising kids.
