I was told by a potential recruit that the lawsuits had determined that Amway/Quixtar was a legitimate business. It appears that is quite true as there are a great many suits out there.
Quoted from http://www.pyramidschemealert.org/PSAMain/news/AmwaySuedasPyramidScheme.html:
In a crucial development that could rock the entire multi-level marketing business, a class action lawsuit has been filed this month against Quixtar (Amway) charging that the company is running an illegal pyramid scheme. (filed in US District court in the northern district of California on January 10, 2007, case number 3:07-cv-00201-EMC.)
The charges against Amway/Quixtar go to the very heart of the company's business practices and most other multi-level marketing (MLM) schemes', that there is no retail "direct selling" opportunity, only an endless chain recruitment program.
The charges are being brought by one of America's most powerful law firms, Boies, Schiller and Flexner. David Boies of this firm represented Vice-President Al Gore in front of the US Supreme Court in the world famous case, Gore vs. Bush that contested the vote counting in Florida after the 2000 election. The other firm partnering with Boies, Schiller & Flexner in the suit is Gary, Williams, Parenti, Finney, Lewis, McManus, Watson, & Sperando, P.L.. in Stuart, Florida. This firm has a powerful track record of successful class action suits against large companies.
