I think what the Fed fears is that, if Donald Trump gets big tax cuts and big spending increases that take effect right now, when the economy is close to full employment, they will have to raise rates more rapidly.

I think it was seen as a symptom that the Chinese leadership may be really scared about their economy.Why would you want to depend more on exports if you're a country that has a stated policy of relying less on exports and more on consumer spending, domestic spending?

People have put a lot of faith in the government's ability to get growth going in China. People have this, what I think, illusion that there are six people in China who really have their hand on every button. And what we're learning is, it's a very big economy and they're not that good at it.

If the government can't get the economy moving again, they have a lot of fundamental problems.

At some point, people may decide that the U.S. stock market has fallen enough. After all, the U.S. economy seems to be getting better, that what happens in China is not going to have that devastating effect on car sales here or how many people buy Apple phones or what happens at - how many people shop at Wal-Mart.

There is the fact that - people have had a lot of confidence that the Chinese leadership could fix what is wrong with their economy so it wouldn't have ripple effects around the world. I think that confidence is being shaken by how difficult it is for them to manage their stock market and their currency.

I think oil prices are down for two reasons. One is, there is a lot of supply. There is a lot of supply because the U.S. now produces a lot of oil and there is a lot of supply because the Saudis seem to want to produce a lot of oil, maybe to punish the Iranians and the Russians.
