Are Building Restrictions Caused by Small Families?
A small family has different economic incentives regarding what type of zoning law to support than large families. For a one-child family an increase in housing costs by $10,000 will increase the family's wealth by $10,000 but the eventual house costs of the child by only $5,000 (assuming the child's spouse pays for half the costs). For a six-child family the eventual house costs will increase by $30,000 in that scenario. So if you ever wondered why people in areas with relatively-high birth rates are more likely to support capitalism, the answer should be obvious.
