 We're urbanizing at well over a million people a week. That means that every two months there's the equivalent of a New York metropolitan area being erected on this planet. Is there kind of an optimum or maximum size to a city? Could you have Tokyo 100 million or Mexico City 100 million? The economy will double in the next 20 years, and the infrastructure needs for economic development turn just enormous. You can't do really economic development without infrastructure. People now know what other people have in other parts of the world, and everybody wants that. Governments need to rise to the challenge. You talk to a developing country, what they'll say is they need foreign investment. I mean, where is the investment going to come from? There's a lot of short-term liquidity in the market, long-term capital, it's still very difficult to get to commit. We've got to bring in new investors. They've got to see that infrastructure is a major part not only of their investment portfolio, but of developing the economy. The whole point of having a city, the whole point of all that infrastructure as a way of bringing people together, create new things, and in particular create wealth. Governments, I think at the beginning, don't understand that they have to put in place policy measures, guarantee systems. Nobody's got the answers yet, but there's a lot of thinking going on. The most important thing is cooperation. World Economic Forum can facilitate cooperation, collaboration among governments, the private sector. Organization, organizations, development organizations, companies like ourselves in the real estate sector who have an impact on property in this area. Looking at case studies of what has worked and what has been very successful and then helping people become aware and sharing best practice and being an advocate of the necessary changes that need to take place. Probably going to be technical solutions and where the folks that can provide technical solutions. You know, it's such an extraordinary group of people that are attracted here. Potentially maybe there can be a little impact on what's going to happen.
