More data from the American Housing Survey. In the last 20 years, the proportion of households with income below the poverty line with the following amenities has increased as follows:
Dishwasher 16% 37%
Washing Machine 56% 64%
Dryer 35% 57%
Supposedly, over the last 20 years, all of the income gains have gone to the rich. Yet, somehow, the poorest households increased their access to appliances that make life more pleasant. These data are taken from Table 2-4. Earlier post on progress in air conditioning is here.
