This was originally published in 1950. As a housekeeping manual, all it really has to say is: housewives don't have servants to help them out anymore, so stop holding yourself to standards developed when they did. Buy furniture that is easy to keep clean, etc. Not so earthshaking an idea now as it may have been in 1950.
What makes the book interesting to me, in 2007, is its basic feminism. The Wrights suggest that men in the family and even male guests at parties should help out with cleanup tasks, gingerly suggesting that it is unfair to leave it up to the women. They present statistics suggesting that while the average American man of the time worked 40 hours a week, the average American housewife put in 60-80 hours a week, and that her labor was just as valid and important as his. In 1950! Betty Friedan was not the first to make these things up.
I ran across this book in the home decorating section of the library (it was right next to the knitting section) and it caught my eye because the title was funny and the spine was yellow. I had no idea what I was getting into, and I was pleased to find it offered some useful perspective on the chronology of middle-class feminism.
