Man you anti-conspiracy guys are really single minded. The entire US government was not behind the conspiracy. You do not need 100% of everyone to simply have a conspiracy all you need is enough to make it happen. No one here is saying that EVERY single person in the government is covering it up. Just that some interested parties with enough power to pull it off were.
Of course the country as a whole is worse off since it happened, more debt, less civil rights, endless wars. Its easy to say that no one wanted this because no one benefited but someone always does. It also may have nothing to do with money, how many wars have been started over religion or power?
Personally I think there is 0 chance a plane hit the pentagon. There is no way in hell a fireball destroyed 99% of the plane and all of the bodies, luggage, EVERYTHING in it. If you have ever seen a plane crash there is always debris, wings, tail sections, seats, luggage, shit all over the place because the explosion/impact throws shit everywhere. The lawn of the pentagon would have been covered in body parts, luggage, seats, garbage, and burn marks. It would have been a horror show the likes you have never seen. It wasn't. Google photos of plane crashes and use some common sense.
Also why are you guys so worried about the passengers of flight 93? If you just blew up 3 giant fucking buildings, killed 3,000+ people, and did billions in damage, and just started a war are you really concerned about one plane of passengers? Maybe they just killed them all, maybe they told them that due to national defense they needed to disappear forever. No one cared about them, and of course they did not let all of their families in on it. Are you just stupid? They told the families what they told you, they are dead.
There is no way that on 9/11 for the first time in recored history did the following things happen. The first skyscraper to ever fall from a airplane impact/fire. The first skyscraper ever to fall from fire alone. The first airplane crash in history to create a fireball so hot that the ENTIRE plane disintegrated into nothing.
