The Fed is totally open.

The amount of currency in circulation is not changing. The money supply is not changing in any significant way.

Monetary policy is not a panacea.

We’ve never had a decline in house prices on a nationwide basis. So, what I think what is more likely is that house prices will slow, maybe stabilize, might slow consumption spending a bit. I don’t think it’s going to drive the economy too far from its full employment path, though.

I don't think that Chinese ownership of U.S. assets is so large as to put our country at risk economically.

Like gold, U.S. dollars have value only to the extent that they are strictly limited in supply. But the U.S. government has a technology, called a printing press (or, today, its electronic equivalent), that allows it to produce as many U.S. dollars as it wishes at essentially no cost. By increasing the number of U.S. dollars in circulation, or even by credibly threatening to do so, the U.S. government can also reduce the value of a dollar in terms of goods and services, which is equivalent to raising the prices in dollars of those goods and services.

In fact, the world needs more nerds.
