There are 20 million teenage girls in the USA, approximately between 10 and 19 years old. Unwanted teenage pregnancy costs the US taxpayers $9.4B/year according to the CDC. That is $470 for every teenage girl in the USA $470 easily pays for free birth control for all teenage girls until they are 18 or 19 years old.
Case closed. Conservative principles, prevention, saving money, saving tax dollars and less govt involved in managing the issues that arise from teenage pregnancy.
I would go even further than that and propose that we pay girls from ages 12 to 20 to NOT get pregnant. Every year, if you did not get pregnant, you get a check from the govt for $1000 at the end of the year.
Real incentive for girls to seek birth control, to seek health care decisions related to their bodies, for parents to educate their children on sex.
Of course, it is not that simple. Sex education needs to start at 12 years of age in the schools, clinical healthcare for reproductive systems needs to be available to boys and girls throughout their formative years, in schools, in the communities and incentives for doctors to discuss these things with their patients.
