Thank you.
I'd like to change the subject completely and ask you what you see as the biggest challenge or risk globally over the medium term. Before you answer, I'd like to give you one candidate and see if you might agree with it.
One concern I have--and that I think many people have--is that the United States deficit is very big, at well over 10% of GDP. That in itself might not be a huge problem, except that I think a lot of people wonder if the United States political process—the Senate, the Congress—is capable of dealing with this kind of thing; we look at their social security problems over decades. So as Canada is so close to the United States, I think this is a concern not only for them but also for me.
Do you see the U.S. President and Congress dealing effectively with this over the coming years?
