I reject the idea that "ruling the world" and other smaller entities would better (or worse) run by women (or men). I don't believe that leadership is gender specific. For years women have struggled to have equality in the political arena in the USA. Many were resistent to voting for women candidates. There was this bumper sticker  "women belong in the house....and the senate" a while back when more women were running for and being elected to congress. Even though it's not 50/50 we've made great strides over the past 15 years. I don't think saying "women should rule everything" is any better than saying men should. I realize that's now that the title of the book can be misleading and that's it may indeed turn off some people from what looks like an interesting read.
