Why should everybody get a house and not have a 2 hour commute? It was the norm for the past few decades, and so your post just reinforces the prior post, except the Roth IRA thing. You can save without an IRA.
At least for Seattle, it seems like the liability for the builder and the costs don't really justify building for less than some un-sellable amount (e.g. $1k / sqft) [0]
