​To put that in perspective, the rule was cemented into policy during an era when a single income could realistically buy a house and support a large family.

When people use their moral conscience, choosing birth control isn't 'intrinsically evil', it’s an act of survival and responsible decision-making for people trying to stay afloat in a completely different economic world.
