Only one minor point from me: the Dan Shapiro quote is a bit off.

> To literally handicap yourself by 50 percent is insanity.

From the figures I've seen, the handicap is in the 25-30 percent range based on the percentage of women in the industry.

But I like his line of thinking. It's an old libertarian argument too: racism and sexism will be rooted out the market by those smart enough to take advantage of the inconsistencies in the labor pool. It's a tremendous opportunity if it's as bad as it seems.
