Again, the starting point is already a patchwork quilt, with different levels of intervention by community.
I would say that seeking some kind of standardization too early in this area is also a mistake. I think it needs the kind of approach that was taken in the U.K. in what was a very successful program, which was a reasonable pilot and a reasonable prototype. It really needs to start at that kind of scale and not raise expectations about private capital or returns on investment, because, as I said before, the primary goal of this kind of intervention is improving effectiveness, which is really about reducing costs to the public purse. Once you can prove that out and demonstrate it at scale, then you can start to worry about whether private or philanthropic capital can be mobilized.
Just to reinforce the point, I do think it's going to be very hard for private investors in the early stages to mobilize on this, not because it's not a good idea, but because there are so many other good things for them to invest in that this comes with a lot of risk and potential reputation risk.
