"I told you so."

'The bigger the lie, the more people will believe it'

?

"Since I entered politics, I have chiefly had men's views confided to me privately. Some of the biggest men in the U.S., in the field of commerce and manufacturing, are afraid of somebody, are afraid of something. They know that there is a power somewhere so organized, so subtle, so watchful, so interlocked, so complete, so pervasive, that they had better not speak above their breath when they speak in condemnation of it."

Quote by:

Woodrow Wilson

Also, Gary Allen said in None Dare Call it Conspiracy: "It must be remembered that the first job of any conspiracy, whether it be in politics, crime or within a business office, is to convince everyone else that no conspiracy exists."

“I believe people of wealth and power conspire with each other to increase their wealth and power, and if you don’t, you’re a fucking idiot”

Another good one, can’t remember who said it however.

"The individual is handicapped by coming face-to-face with a conspiracy so monstrous he cannot believe it exists. The American mind simply has not come to a realization of the evil which has been introduced into our midst. It rejects even the assumption that human creatures could espouse a philosophy which must ultimately destroy all that is good and decent."

J. Edgar Hoover, as quoted in The Elks Magazine (August 1956)

Never heard it. I do remember being told "It's only paranoia if they're REALLY out to get you"
