There's a book somewhat related to this idea called The Two Income Trap. I haven't read it yet, but recently read a good book review of it[0] that discusses the extra competition created by two-income households and tries to vet the book's evidence. It also discusses the related problem that comes from treating "good school districts" as a positional good, causing a negative externality of over-competition and consumption beyond the intrinsic economic benefit of that good.
