Eh I moved my family (stay at home wife and two kids). If you are willing to live outside of the trendy areas you can find OK places. Unfortunately single family homes (like we inhabit now) are not rent-controlled. We're currently trying to decide between moving to a multi-unit building with a 3-bedroom place or staying and putting up with the ridiculous rent. The multi-unit building would still be high rent but at least it would be locked in forever.

It definitely costs my startup employer (and myself), especially factoring in preschool. It also steals a job and "juice" from the local economy - we'd have already hired a nanny if rents were merely 2x a normal city, and we'd happily spend more buying from local craftspeople. The money goes into my landlord's retirement account basically doing nothing.
