This is a citizenry education problem, a media problem but not a metrics problem. These metrics are built and used by people who do apply multiple measures - every day. If you are in a trading or macro oriented role, you will not be using just one figure. You will make the effort because your incentives and training encourage you to do so. The non-specialist, which is most people, is never going to have a set of metrics which make it easy, because no metric can overcome all the practical and technical issues strewn across the path to producing it.
