Repealing the 1945 Antitrust Exemption for health insurance companies would lower premium. Repealing it would cause health insurance companies to compete more with each other for policy holders, and to do that they would have to offer lower premiums. Competition between businesses is always better for the consumer because they get better products for a cheaper price.
I believe that repealing the 1945 Antitrust Exemption for health insurance companies would lower premiums because it would force the companies to compete more for business, and therefore lead them to offer more competitive prices in the market place. Furthermore I believe the insurance health care industry to be comprised of little more than a few cartels who lobby for favorable legislation and are able to charge favorable prices. By breaking up these cartels would also break up their influence, which is by most accounts detrimental to the interest of most Americans.
