I am an avid fan of Jane Austen's. I can't tell you how many times I've read pride & prejudice, which if I was writing that book, I'd subtitle it economics 101.
Women may have pretended not to know about economics but they know. Well there are always outliers of course. If you want there never to be an issue with money in the household, you put the wife/woman in charge of the finances. If women were in-charge of the FED there would never be a problem in 2008 and there would be no problem in the future with any countries finances.
