This is a Budget that, like the one before it, has said that GDP cannot be the sole measure of success. I think even the members opposite surely will acknowledge that the irony of GDP itself is that it is both too broad and too narrow a measure for us to use to measure the success of an economy. As I have said many times in this House, Kuznets, the economist who designed and created GDP, said himself, at the creation of this tool, don't use it as a tool to measure the success of a nation's economy. It is a useful number and it is a useful insight, but it is not a measure.
