Markets are designed to allow individuals to look after their private needs and to pursue profit. It's really a great invention, and I wouldn't underestimate the value of that. But they're not designed to take care of social needs.

When it comes to social consequences, they've got all different people acting in different ways, very difficult to even have a proper criterion of success. So, it's a difficult task.

One of the myths propagated by the enemies of Israel is that there is an all-powerful Zionist conspiracy. That is a false accusation. Nevertheless, that AIPAC has been so successful in suppressing criticism has lent some credence to such false beliefs.

As a society we can't live without moral considerations. We do have to protect the public good. And markets are not designed to do that, so we need a political process.

The US needs a cap and trade system with auctioning of licenses for emissions rights. The revenues from these auctions can be used to launch a new, environmentally friendly energy policy. That would be yet another federal program that could help us to overcome the stagnation.

To be successful, you need leisure. You need time hanging heavily on your hands.

My approach works not by making valid predictions but by allowing me to correct false ones.
