This NY Times piece discusses the demand for 400 square foot apartments in hip parts of NYC. In housing markets where the price per sqft is high, this must mean that the quality of the area is terrific but demand curves do slope down and middle class people can only afford to live in such areas if they reduce the number of square feet they consume. This article walks the reader through the costs and benefits of living in such housing. I did not know that Mayor Bloomberg seeks for more people to live this "Tokyo" style life. Can Americans change their ways and downsize? I would guess that there is certain segment of the population who are neat enough and don't mind having their bed so close to their kitchen.
