Cold-turkey deficit reduction would cause a significant recession. A recent analysis by the Congressional Budget Office estimated that going headlong over the cliff would cause our gross domestic product, which has been growing at an annual rate of around 2 percent, to fall at a rate of 2.9 percent in the first half of 2013.

If you look at the studies coming out of the Congressional Budget Office, the number one thing that's going to blow a hole in the deficit as we go forward 20, 30 years is government spending on healthcare.

Tax increases appear to have a very large sustained and highly significant negative impact on output.

The stock market crash in October 1929 didn't destroy a particularly large amount of wealth or make people highly pessimistic. Rather, it made companies and consumers very unsure about future income, and so led them to stop spending as they waited for more information.

We're losing biodiversity globally at an alarming rate, and we need a cornucopia of different plants and animals, for the planet's health and our own.

We need a government, not politics. Because there's too much politics. Of course there should be debate. But there seems to be so much pettiness and not enough good faith. It is civilized to agree to disagree, and this idea is slowly disintegrating. The great statesmen of the past knew this, and I think it helps drive civilization.

My personal opinion is that I don't ever do jokes that are about disability or cancer or what are seen as 'edgier' topics. I've been affected by those things myself, and I think that comedy should be a safe place for people.

If inequalities of taxable wealth backing up a government service are construed as denying equality before the law, then there is no solution but to have every government service whatever financed out of Washington.
