I'd like to add, what we see when we talk about additionality—and we think about how this idea of our talking about not just philanthropic resources, but also social investments as well—is that it quite genuinely grows the pie. We're not in any way against the growth of philanthropy. We obviously are hugely supportive of that, but we've recognized we often will come up to limits there. When we talk about profit motivations of the kind of order that I'm talking about, which can afford a 7% and that kind of reasonable rate of return, it opens up a different pool of money. Foundations can talk about investing through their endowment capital. It doesn't just have to be from their grants budget. High net worth individuals may engage. Even everyday citizens might somehow collaborate to invest. In that regard, we generally tap new resources that are also additional. I think that's pretty critical for a lot of the issues you raise.
