Ms Wolf could have saved herself considerable trouble had she simply titled her book: Supply and Demand: How Seventy Million Working Women Created a Lower-Paid Society. With a few simple graphs, she probably could have wrapped the whole thing up in less than 10 pages.

I always find it remarkable, and perhaps even a little depressing, how few people are able to grasp that the primary consequence of the addition of 70 million working women, all of whom were already consumers, to the labor force, could never have been anything else but to lower wages. 

One can debate whether female workers are more or less productive than male workers, and one can certainly debate whether the societal effects were beneficial or negative, but the one thing that cannot be denied, on logical, theoretical, historical, or empirical grounds, is that the post-1950 doubling of the female labor force has had a severely depressing effect on American wages.
