I think there's a multi-dimensional answer for that question. There are a number of benefits back to the government.
One of the benefits is that social finance provides a mechanism for creativity. There is so much innovation happening in the social finance ecosystem, and it's created by the people delivering the services. One of the challenges that exists with government financing programs is that the time it takes to create the program and the rules you have as a government to implement programming essentially contain them in a certain set of actions. Private individuals, charities, and non-profits are looking for innovative and creative ways of fixing social problems without the burden a government agency might have in terms of how it actually creates programming, so the ability to create new innovations is massive.
Think of the analogy to technology. Up until the mid-2000s, the people defining how we engage with technology were Google, Microsoft, and IBM. Steve Jobs created the iPhone, and now we have millions of apps created that define how we engage in technology in a fundamentally different way. You open the door to both charitable and private sector creativity, and you can find mechanisms to deliver government programming differently.
The other benefit is the ability to save funds for the government. I think there are a number of ways those savings can occur, and I can go into detail if you like. It's one of the things that...not just saving money, but finding new pots of capital to inject into a certain social sector that government alone can't address. Social housing is a perfect example of that.
It's trying to tap a number of different concerns the government has when it delivers social programming.
