Yes it will drop abortion rates significantly but will not necessarily drop the amount of women on welfare, which in the long run is where a shit ton of taxes are going. The welfare whores won't care if there is contraceptive available or not...
Now I believe the women AND men who are in situations where they haven't planned the pregnancy should step up. I did not plan my pregnancy and was on birth control, even though I was trying to prevent a pregnancy didn't make me not step up. I have not relied on "the system" to provide for me or my daughter nor did i run to planned parenthood to kill the baby growing in me. I grew up, got two jobs and am going to school to better myself. If I can do it so can all the other women in a similar situation. Shit happens and plans change.
