The US isn't the only country in the world with big families; there's seemingly nothing exceptional about us (in that regard) that requires the pickup truck and 3-space garage where other countries get along fine. Part of the reason they get along fine is because they allow grocery stores to be built on residential corners, so that you buy 3 gallons of milk every other night on your way home rather than driving X miles to load up weekly.
