I don't want to pick on Deutsche Bank, but I think the world of the regulated financial conglomerate, it is a strange thing. There is nothing in common between writing checks and running branch offices, issuing credit cards - those are good businesses, but they really have zero in common with M&A advice. They're a different customer.

Everybody is looking at their base business and saying, "What else is it? Sure, we do this, but while we're doing that, what else do we know about our customer, and what does that enable us to do?" That comes from the access to information and the ability to analyze it with a speed they never had. I think everybody is thinking that way.

You see a wave of populism in the world. There is something wrong. This maybe because of technology. The ability of people to reach their own news sources now, and create different views, is really unbelievable. There is a desire for change. There is a millennial generation that doesn't like what they're seeing, but doesn't quite know what the solution is.

Remember, for 5,000 years people probably rode those horses. They probably felt that horses were a permanent part of civilization. Everybody has had this moment.

I do think [in USA] is a need for change. There is something wrong when you have $20 trillion of debt and crumbling infrastructure at the same time, and really fewer people employed than have been. Something is wrong.

A big secular thing going on is technology and deflation. This is where I think millennials are getting that it is an improvement in life, and they're taking advantage of it.

Do people have confidence? I think the real confidence you need is the confidence in your outlook, and I think people are pretty confident it is a low-growth world.
