Also, you can blame the government

We have this new book at work, How To Feed Your Family For $75 A Week.  It's a reprint of a title from about 1993, How To Feed Your Family For $30 A Week -- something about Labor governments seems to inspire that sort of thing, I guess.  It's full of useful tips like reducing the fat content of your milk by adding water, and using the same tea bag three times. 

The best bit, though, is the opening chapter, which claims that "so-called 'progressive' social legislation is driving up food prices".  Yes, guys, gay marriage is the reason your groceries cost so much.  And multiculturalism, too.  Good stuff.
