This is the edited highlights from the Wikipedia article:
NESARA is an acronym for the proposed National Economic Security and Recovery Act, a set of economic reforms suggested during the 1990s by Harvey Francis Barnard. Barnard claimed that the proposals, which included replacing the income tax with a national sales tax (see also FairTax), abolishing compound interest on secured loans, and returning to a bimetallic currency, would result in 0% inflation and a more stable economy. The proposals were never introduced before Congress. NESARA has since become better known as the subject of a cult-like conspiracy theory promoted by Shaini Candace Goodwin, who claimed that the act was actually passed with additional provisions as the National Economic Security and Reformation Act, and then suppressed by the George W. Bush administration and the Supreme Court. Other people have adopted and embellished Goodwin's ideas.
Harvey Francis Barnard, a Louisiana graduate in systems philosophy, and an engineering consultant and teacher, created the NESARA proposal during the late 1980s and early 1990s. He printed 1000 copies of his proposal, titled Draining the Swamp: Monetary and Fiscal Policy Reform (1996), and sent copies to members of Congress, believing it would pass quickly on its merits. Based on a theory that debt is the number one economic factor inhibiting the growth of the economy, and compound interest the number one "moral evil" and reason for debt, Barnard made several other attempts during the 1990s to draw political attention to the problems he saw in the US economy, and his suggested economic recovery proposal based on the root causes he determined. After these did not succeed, he decided in 2000 to release the proposal to the public domain and publish it on the internet. Barnard established the NESARA Institute in 2001, and published the 2nd edition of his book in 2005, retitling it Draining the Swamp: The NESARA Story - Monetary and Fiscal Policy Reform.
... Soon after Barnard released NESARA on the internet, a user known as "Dove of Oneness" began posting about it in internet forums. "Dove of Oneness" has since been identified as Shaini Candace Goodwin, a former student of The Ramtha School Of Enlightenment, referred to in the media as a "cybercult queen..." Goodwin refers to "White Knights," most of them high-ranking military officials, who have since been struggling to have the law implemented despite opposition by President George W. Bush...
Since Goodwin began commenting on NESARA, other internet-based conspiracy theorists have latched onto it. One supporter, Sheldan Nidle, ties the imminent NESARA announcement into his years-old prophesy of an imminent large scale UFO visitation by benevolent aliens... Jennifer Lee, who used to publish internet NESARA status reports almost daily on her now defunct site, discussed a host of other-worldly and "inter-dimensional" beings who are helping behind the scenes to get NESARA announced...
Criticism and comparison to a cult
Barnard became aware of Goodwin's description of NESARA before his death in 2005. He denied that NESARA had been enacted into law or even assigned a tracking number, and condemned Goodwin's allegations as a disinformation campaign. Goodwin, for her part, dismisses the NESARA Institute as a disinformation front for the Bush family.
Some NESARA detractors claim that NESARA is a cult designed primarily to provide an income to Goodwin and others. They point to the fact that Goodwin, Lee, and Nidle frequently ask their readers to donate money. Goodwin, who also asks readers to donate their frequent flyer miles, claims that she needs and has used the funds to travel to various locations around the world to secretly meet with high-level government officials about getting NESARA announced.
Some NESARA supporters also make the claim that otherworldly beings are working to get NESARA announced. These include a "channeled" cosmic being called "Hatonn" (an android Pleiadean), and another named Sananda. According to some Ascended Master Teaching proponents such as Joshua David Stone, Sheldan Nidle, and Luis Prada, Sananda is the "galactic name" of Ascended Master Jesus, which he uses in his role as Commander-in-Chief of the Ashtar Command flying saucer fleet. Pallas Athena is regarded as being the Vice-Commander of the saucer fleet. Ashtar (Ashtar Sheran) is regarded in these teachings as being third-in-command. Saint Germain, an Ascended Master borrowed from the I AM Movement and the Church Universal and Triumphant, along with benevolent aliens from the Galactic Federation, are also frequently mentioned (most prominently by Nidle) as working towards the NESARA announcement. The designation of George W. Bush as a disguised reptilian often co-occurs with this claim. Goodwin has claimed that Ascended Master Saint Germain has come down from the etheric plane to physically meet with heads of banks and world leaders regarding the NESARA announcement.
The prominence of failed prophecy also lends support to the cult theory. NESARA supporters often tell their readers that the NESARA announcement is going to happen in a matter of days. These claims have been made too many times to enumerate, without ever coming to fruition. According to the documentary Waiting For NESARA, the claim was also made prior to March 2003 that George Bush was planning the war with Iraq only to further delay the NESARA announcement. It was prophesied that spiritual beings and UFOs would intervene with Bush's plans and prevent the war.
A June 2006 complaint to the Washington consumer protection division accused Goodwin of using the NESARA story to defraud a 64-year-old San Francisco woman of at least $10,000. The woman's daughter said the actual amount is much larger, in the hundreds of thousands.
So it appears that there are 2 NESARA's:
1) a great Economic Idea that would Transform the world
2) a hi-jacking of the idea and attaching it to "Disclosure"
As long as we all know the difference, we can consciously choose which 'NESARA' we'd like to support and not end up in the group where we might feel a little bit uncomfortable :P
