The main idea behind those is that all that stuff is traditionally women's work. They knew they wouldn't be able to convince men to take up half the housework right away, so socializing what was traditionally women's work was seen as necessary to women's liberation and economic independence. If there are community kitchens and cafeterias, women won't be forced to be in the kitchen all day. If there are free abortions and universal daycare, women won't be saddled with watching kids all the time. That kind of stuff.

What's the book by the way? I'd love to read it.
