On the supply side, for innovation, you'd say, go look at those R&D budgets, and they haven't moved in the last 20 years.

Innovation is often the hidden thing, because we can't put numbers to it. And yet it's the thing that defines the way we live, the things we'd like to have for everyone whether it's health or education.
