If a medicine is too expensive, should a hospital make its own?

When Marleen Kemper was a child, she watched two of her primary-school classmates get ill. One had a brain tumour, and the other contracted an infection in his gut. Both of them died. Kemper was around ten at the time, and knew that she didn’t want to see another friend perish. She told her parents she wanted to do something that would prevent others dying. She wanted to be a doctor.
