Birth control pills save insurance plans money, making insurance premiums cheaper.
Births and congenital surgery are expensive.
Pills are made in factories and are cheap. Bangladesh offers free birth control pills.
That is an economic point and a good one, but it is not relevant. Saving private companies/individuals money is not the proper role of government. BC pills would not save catastrophic coverage plans money. Medical insurance is an economic transaction, and it should be up to the customer and the insurance company what is and what is not included. FedGov should not be involved at all. If they are to be involved, requiring catastrophic coverage should mark the upper limit of that involvement.
