Daniel, as everyone knows, cutting taxes increases receipts.
When taxes are cut, receipts usually go up. But they also usually go up when taxes are raised. Receipts tend to go up regardless of small changes in marginal tax rates because they're outweighed by inflation, economic growth, and population growth. It's a canard to say because revenues went up when taxes were cut, the tax cuts caused the revenue growth. Plus the logical implication of a cause-effect relationship would be that receipts would be highest if taxes were zero. The Laffer Curve is obviously correct at the extremes: both zero taxation and 100% taxation will bring in no revenues. Other than that, to say that lowering taxes cause increased revenues is speculation: first, we don't know what that curve looks like between the extremes, and second, we don't know where on that curve we would be.
If you live or work in New York all terrorist acts are existential - you could be blown up.
Sure. And I could get shot and killed; does that make every gun crime an existential threat? If so, what does Guiliani have on that issue, and any other issues that might cause my death (getting hit by a car, being misdiagnosed by a doctor, that staph infection I had last summer)?
To say that any event in which you might die is an existential threat I think demeans the meaning of the phrase, and it's clearly not what Giuliani was implying. Of course the the threat of death and destruction should be taken seriously, but let's not pretend anything they will do will cause the demise of the nation.
And add to that the fact that he had no real anti-terror policy. He said we'd "stay on the offensive," and that "weakness invites attack." Well, people who are willing to blow themselves up aren't deterred just because their opponents look strong. So even in what was supposed to be his strong suit, he was an empty suit.
