501(c)(6) organizations include Business Leagues, Home Builders Association, Chambers of Commerce, Real Estate Boards, etc. such as the U.S. Chamber of Commerce political action committee and the National Football League.
The National Football League operates as a 501(c)6 non-profit association and has operated that way since the 1960s. This in no way means the NFL is a stranger to profit. It is in fact one of the most profitable sports leagues in the United States, making over $9 billion in profits from 2011 to 2012, according to Business Insider.
Friggin Tax Code. There is no reason for this exemption. Even in the 60s. Its time to scrap the damn code and start over.
