It's down to training on the job. First of all, the economic policy of the late 1980s and early 1990s was to attract investment into Wales based on the fact that we had lower wage rates than anywhere else in western Europe. Those days, thankfully, are gone. We now attract investment that is well paid. We have investors coming into Wales who would never have come here 20 years ago. They wouldn't have seen Wales as a place where they could get the skilled, well-paid workforce that they require. That's why, of course, we have the economic action plan. It's why we've put so much emphasis on skills through schemes like Jobs Growth Wales, to make sure that our people have the skills they need to earn more when investors come to Wales and when they set up their own businesses. That is the answer, to my mind, in making sure that we see GVA per head improve over the next few years.
