If you are a woman of child bearing age your premiums might go up 50%[or a lot more-- IDK]? Pregnancy is very "high-risk" and rather likely. Men are responsible for that "certain disease" also -- it takes two to tango

You could use the same argument for property taxes -- if you have no children in school you should not have to pay for the school district. In reality, the quality of the schools that you pay for in your property taxes influences the value of your home and the community that it is in.
No one wants to take the heat to deal with the real problems with healthcare for the 60%? of the people that are not entitled to receive Medicaid and Medicare now. That will boomerang on the government -- really it is right now.
