It is a fallacy to think that government "interference" has caused the problems in our dysfunctional healthcare system. In fact, just the opposite is true. In 1945 insurance companies were basically turned loose on the public, free to set their own rules and not worry about anti-trust regulation like other corporations.
As stated in an earlier post, for the people that are covered through employer provided insurance, they have very limited choice in their coverage. The employer buys insurance that covers the most for the least amount of money. Fertility is certainly a part of ob/gyn medicine, and should be included in insurance that provides that kind of coverage.
A government run public option would give people the "choice" to buy a universal plan. They would also have a choice to buy private plans. The more choices, the better, and the cheaper, for the consumer. As the public option is proposed now, only those not covered by their employer, or those unable to find affordable insurance in the private sector would be eligible to buy the public option insurance.
