American communities require that new housing meet quality requirements that are very high by world or even Western European and Japanese standards. These requirements are designed by middle-class architects, planners, and citizens in conformity with what they believe is decent housing. But their concept of decency far surpasses what is necessary for human health and safety. Consequently, all new American dwellings are too costly for low-income people to occupy without direct subsidies. But subsidies are provided for only a few of the many households with incomes low enough to be eligible for them. So poor people live in unsubsidized older dwellings.
