Okay. Over that number of years, the ratio of return is 6:1, but you have to be patient. Mr. McCallum is right: you're not going to get $6 for every $1 you invest tomorrow or even in the first three electoral cycles. Why? Because the kids need to grow up and get into the labour market. Once they're there, the returns start coming much more quickly. If we can be patient, it's an enormously valuable investment, but it means we have to rethink economic growth.
