If you were a corporation needing financial services, and I can give you something better, faster, and cheaper across 12 products as opposed to eight, that's business. I'm doing it because I'm serving you; I'm not doing it because I want to be universal.

I advise other companies' CEOs, don't fall into the trap where you go, 'Where's the growth? Where's the growth?' Where's the growth?' They feel a tremendous pressure to grow. Well, sometimes you can't grow. Sometimes you don't want to grow. In certain businesses, growth means you either take on bad clients, excess risk, or too much leverage.

If business doesn't thrive, it hurts America. We need improved relations, more collaboration, more thought and more consistency as we go about trying to make sure we have the best country in the world. Not scapegoating and finger-pointing.
