This exemption has allowed the Health Insurance Industry to work together to collectively establish rates on premiums and manipulate other costs associated with payments to doctors for treatments. We see how well being exempt from antitrust laws has helped Major League Baseball - with multi-million dollar contracts for players and billion dollar ballparks in NTC. The affordability of going to a Major League Baseball game has long since left the average American to enjoy a day a the ballpark with their family. Now, the affordability of Health Insurance is beginning to cripple the financial underpinnings of the nation.
Most Americans, I'm willing to assume, didn't know that the Health Insurance Industry was exempt from Federal Antitrust laws. If Congress repeals the law, it would allow them to break up large Health Insurance Companies the same way that they did to Ma Bell (AT &T) back in the 1980s. This make the most sense, and if the Health Insurance Industry wants to compete across state lines, then do it without the security blanket of the McCarran-Ferguson Act.
