I wish there was more than that baby-sitting co-op to support those ideas. One story doesn't make a proof. Krugman brings it up all the time - so the hopes of the nation apparently rest on a single baby-sitting co-op.<p>It's been too long since I thought about it, but back then I felt there were some aspects missing from the story. Must think about it again, but overall, it is a very limited experiment, hardly the same as a full economy.<p>Also, doesn't the co-op story show that people can also create their own money? If lack of money was the problem, why don't they just exchange services and products (I mow your lawn and you clean my car)? Money is just a tool to make exchanges more efficient, but it's not that without money they become impossible.<p>Of course, it is always appealing to blame everything on some rich elite.
