① The United States is facing a housing crisis: Affordable housing is inadequate, while luxury homes abound (充裕) , and homelessness remains a persistent problem. Despite this, popular culture and the housing industry market happiness as living with both more space and more amenities (便利设施). Big houses are advertized as a reward for hard work and diligence, turning housing from a basic necessity into a luxury.

② This is reflected in our homes. The average single-family home built in the United States before 1970 was less than 1,500 square feet in size. By 2016, the average size of a new, single-family home was 2,422 square feet. What’s more, homes built in the 2000s were more likely than earlier models to have more of all types of spaces: bedrooms, bathrooms, living rooms, dining rooms, recreation rooms and garages.

③ There are consequences of living big. As middle-class houses have grown larger, two things have happened. First, large houses take time to maintain, so cleaners and other low-wage service workers are required to keep these houses in order. Second, once-public spaces, where people from diverse backgrounds used to come together, have increasingly become privatized, leading to a reduction in the number of public facilities available to all, and a reduced quality of life for many. Take swimming pools. While in 1950, only 2,500 U.S. families owned pools, by 1999 this number was 4 million. At the same time, public municipal pools were often closed, leaving low-income people nowhere to swim.

④ The trend for bigger housing thus poses ethical questions. Should Americans accept a system in which the middle and upper classes enjoy a luxurious lifestyle, using the low-wage labor of others? Are we willing to accept a system in which an increase in amenities purchased by the affluent means a reduction in amenities for the poor?
