I want to remind the Opposition and people listening at home that, when GDP was first introduced, our gross domestic product, it was a controversial measure and it was disputed for many decades as to what exactly should be included in GDP—that, at present, some things that we value, that have enormous value to us, never make it into GDP. Famously, Marilyn Waring has pointed out that women's work doesn't get counted in GDP, that GDP has some extraordinary difficulties in it in terms of things like—the production of milk powder counts for GDP, but breastfeeding a baby doesn't. So it's interesting what we do and we don't value.
