Those young women who made the decision to have sex not knowing if the individual they "Tangoed" with would help with any costs or work will soon learn that it was a poor decision. Sheltering the consequences of ones actions is not an affective way to direct behavior for the masses. That young girls friends will see that it was hell, and their parents will learn it was an expensive decision, and then those other girls and their parents will do a better job being responsible citizen. I shouldnt have to pay for coverage that is ultimately needed because of poor parenting.
And yes, with any statistical examination there will be a small percentage of people that statistics work against, IE. the less the 1% of pregnancies due to rape.
