I think the Fed is not designed to have effective tools to deal with the economy. It should settle for just controlling the money supply. And - if it insists, it can worry about inflation.

One day we will have more inflation, and our bonds will bleed like a pig. The only reason for buying long bonds is short-term or as a desperate haven for terrorized investors. But the potential to make longer-term real money is naught.

Low-cost, high-grade coal, oil and natural gas - the backbone of the Industrial Revolution - will be a distant memory by 2050. Much higher-cost remnants will still be available, but they will not be able to drive our growth, our population and, most critically, our food supply as before.

I think the U.S. should assert its leadership in a more effective way.

You can't run the economy on BMWs alone. If the average person is in a pickle, how do you have a healthy economy?

I think about my friends all the time when I'm designing. That's always an arbiter. Would Katy wear this? Would Rihanna wear this? Would Sia wear it? Would Miley wear it?
