That other things, like retarded government expansions, goof-ball regulations, and socialism in general spend money faster than it's coming in and cause economic contractions is what leads to long term loss of government revenue.

Anyone claiming that Bush could have done something to prevent 9-11 but refuses to specify is merely exercising his hot air generator. You have nothing to debate because you have nothing to say.
What could have prevented 9-11 is if someone had taped Madeline Albright's mouth shut when the missile launch was ordered so the dumb broad couldn't warn Pakistan, and thus bin Laden, that loud visitors were coming.
Killing bin Laden.
That would have stopped 9-11.
Not much else would have.
