What is all about Freemasons, Illuminati and the New World Order?

@ the bricklayer - if there is nothing to hide and there is no secrecy as you say then why is there a hierarchy where the people above you know more than you? Then if that's the case how do you know there isn't anything to hide seeing as that your not told everything by the powers above you? I've also heard that the grandmaster - the guy at the top of this system is unknown to all. Seems shrouded in mystery if you ask me.
