Your posit fails to account for the current state of humanity, where children do not have parents, are treated as cattle by the state and have no monetary value until they are working age...until then, you can abort them, dispose of them and leave them in childcare as much as you like.
Actually, just the opposite is true, and even *more* insidious. That is, in one way or another, children are assigned as property to one or more adults. Children without a “legal guardian” are in effect, runaway slaves.
