George Orwell is a pinnacle writer, for his combination of moral insight and literary writing.

Providing health care is like building a house. The task requires experts, expensive equipment and materials, and a huge amount of coordination.

Most people are squeamish about saying how much they earn, but in medicine the situation seems especially fraught. Doctors aren't supposed to be in it for the money, and the more concerned a doctor seems to be about making money the more suspicious people become about the care being provided.

The vast majority of doctors really do try to take the money out of their minds. But to provide the best possible care requires using resources in a way that keeps you viable but improves the quality of care.

I was born on a plantation, and things weren't so good. We didn't have any money. I never thought of the word 'poor' 'til I got to be a man, but when you live in a house that you can always peek out of and see what kind of day it is, you're not doing so well. And your rest room is not inside the house.
