1) the 30+ year war on drugs, still in effect because the masses believe the illusion that being excessively tough on crime makes for a better society.
2) 12 USC being modified by the Trading With the Enemies Act of 1917 to include "United States Citizen" [1].
3) House Joint Resolution 192 of June 5th 1933 banning gold and silver as currency, ushering in a bankruptcy with the trimmings of Keynesian Economics [2].
4) "9/11 changed everything".
5) Most relevant, NSPD-51 pulling all branches of government under the Executive during Bush II [3], and none of us caring.
Every one of the above is an illusion; handwaving by bureaucrats, that were integral for bringing us to where we are today. Why do you choose to accept/live by the above illusions? because everyone else is?
